Bolting is an ethical issue that is discussed at length in the climbing community.
The ethics are very strong in Yosemite and therefore there are almost no bolts and all the climbs are done using removable gear. (also called trad gear).
I'm also baffled that you compared a couple micro pieces of metal to the disruption that a road provides to the environment. Or even compared to skiing resorts, mountain bike trails etc. In my experience climbers are some of the most ecologically respectful people out there.

It's more because it's El Capitan. It's a special place. I get why climbers feel attracted to it but it's more important that it be protected than people, in ever increasing numbers, get the pleasure of climbing it. Look at what's happening at Everest. The feat's been accomplished, no need for everyone else to do it too.
