That's a stupid argument.
Let's say that you and your gf/wife decide to go camping at a nice spot you know about it's beautiful and quiet, but it isn't a developed camp ground. Well about an hour after you get there and set up camp a group of 10 rednecks show up and start drinking, swearing, playing death metal and riding around on dirt bikes. You can't tell them to be quiet because they will probably beat the shit out of you, you can't call the cops because it's 20 miles to the nearest pay phone and even if you could call them they couldn't do anything because you aren't in a developed camp ground. So you either have to put up with the bullshit or drive for hours to who knows where to find another place to camp.
Basically the rednecks ruined your enjoyment of a nice spot.
I've heard the argument that you don't have to clip those extra bolts but it's bullshit. Just the fact that those bolts are there wrecks the climb. I've done a number of slab routes where half the adventure of the climb is not knowing exactly where the route goes. If you leave a trail of bolts you take away part of the adventure.
Climbing is dangerous, and that's part of the excitement of doing it, but you want to dumb it down so nobody breaks a nail.
