To me the issue was always damage to the environment, ie bolting natural features like rock, so if bolts are removed, then new holes drilled and bolts replaced, the damage is doubled. It would be great if there was a way to regulate it better but there doesn't seem to be. So, if bolts are chopped on a popular route we probably end up with more replacement bolts, more damage.
Personally, I wouldn't have thought the left side start pitch was worth placing two bolts for when you can do the right side with natural pro. On the other hand it seems that exit 32/38 routes must have somewhere around 95% bolt protection and it sure has opened up a lot climbing that wouldn't otherwise exist.
