It's an interesting question. I think the answers are many, but none are complete. I believe the existence of bolts in the Gunks is more due to different personalities than anything else.
The bolt ban yorick refers to is something that transpired in reaction to a bolting war that flared up almost exclusively out at Lost City. A new generation of cutting edge climbers were putting up stuff that would remain X without a bolt ... stuff like Clairvoyance or New Mutants. Bolts were placed, bolts were smashed. (Some contend that Clairvoyance can be protected without the bolts, but if you've ever been up there to look at where the wire "placement" supposedly can be made, you'd understand why a guy like Gruenberg, known for his major X routes, would place the bolt.)
This all happened in the context of the national climbing debate that was raging at the time over pre-placed protection. It is indeed ironic that several classic Gunks routes had been created with this very technique long before this huge debate flared up.
In looking for answers, I guess one should first take into account all the aid pins that had been hammered into the Gunks and then subsequently used for FFAs later on. Even though Stannard brought clean climbing ethics to the Gunks, he was using McCarthy's aid pins on Foops during the FFA. On Warp Factor 1, Williams and DuMais drilled a bolt at the crux for aid. Stannard used it to free the route.
Then again, people can argue that those original aid pins (and bolts) were placed from the ground up. And they'd have a point.
Ultimately, there seems to be a small fudge factor in the traditional history of the Gunks. And it's hard to fathom why some routes were allowed to be bolted and others not. As previously metioned, one factor is definitely the one concerning whether a route could be protected at all without a bolt or two. But it also seems to be about the personalities of the bolt placers and how they were regarded by the rest of the community. In addition, what were the personalities of the people who resisted bolting? Bolting occured during McCarthy and Stannard's day, yet they never smashed a bolt. Ken Nichols on the other hand made it his jihad to smash every bolt he could.
Why exactly was Arrow or Never Never Land allowed to be bolted and New Mutants not? Why does Beer and Loathing remain bolted to this day ... yet Pumping Pygmies had the insitu gear removed immediately?
I also think that in 1986 there was resistance to the next generation of climbing. For some reason at that time, American climbers were strongly divided over the direction that climbing was going in.
At the Gunks, you had guys like Scott Franklin who had established a 5.13 from the ground up ... but was reviled for placing three bolts on New Mutants. Guys like Mileski and Gruenberg, known for their serious routes, took it on the chin for placing one bolt on Clairvoyance. Dave Lanman, who establshed several hard 12s tradtionally, had his bolts on Running Man smashed. And there's the great story about how Frank Minunni confronted Ken Nichols after he established Future Shock with one bolt -- explaing to Nichols that no matter who does it, if the bolt is smashed on the route, he was going to come after Nichols. (The bolt is still there.)
My guess is that Lanman, Franklin and others were making a decision that flew in the face of the generation that immediately proceeded them. Clune, Raffa, Romano and others had devoted their energy and passion to putting new, hard, bold routes up in tradtional style.
Of course, there again (with the notable exception of Romano) their generation changed the rules of the past as well. Instead of pre-placing protection, they would work routes in seige parties and yo-yo routes ... not pulling the rope after each attempt as had previously been done. They even went as far as to top-rope To Be or Not To Be before making the FFA. And even some the most venerable Gunks traditionalists put a bolt or two up on the cliff ... including our own RG on Farewell to Fingers.
Still, looking back earlier than that, there are these hard-to-fathom exceptions to the tradtional history of the Gunks. Pas De Deux had its pins placed on rappel before the lead ... even though it was possible to place them on aid from the ground up ... why? The same goes for Crowther on Arrow. The bolts could have been placed from the ground up. Hell, Scotty banged in pins on Survival from the ground up. And then ... how does one account for Russ Clune (a strong traditional Gunks climber with a record of bold ascents) cutting down a tree and placing a bolt on rappel ... at Skytop?!
Anway ... I think it comes down to this ...
Pre-1986 there were few climbers who placed bolts. In the early days, the folks who placed bolts seemed to have generally put a lot of thought into their actions and made conclusions about the protectability of their routes, and more importantly, there didn't seem to be anyone who took it as their duty to remove or smash their bolts if they disagreed with their actions.
And the climbers who didn't pre-place or put bolts in ... well ... they made their FFAs in bold style and for the most part, climbers feel it's important to honor the style of the first ascentionist. In addition, many of the climbers who did place a few bolts were alos known for their bold, traditional climbing. (Had Clune and Raffa decided to place a bolt or two on To Be Or Not To Be, I am certain they would still be there today.)
Personally, I think that folks like Mileski, Franklin and Lanman also put thought into their bolting. They had earned their stripes as Gunkies and they were protecting visonary climbs that couldn't be protected in any other manner. But conversely, the Gunks community was probably deeply troubled in 1986 by the rise of sport climbing. While we know the Gunks can survive a few bolts and retain its traditions, at the time, you can imagine the fear that the community must have felt at the prospect of the Trapps or Lost City turning into another Smith Rocks. (I don't think that would have happened, but one cannot deny the fear of that possibility was justified.)
So ... like I said ... many answers ... none complete.
Almost certainly folks like DW and RG can illuminate this subject far better than I can.
