Depends on what kind of rock. I dont know about out there, but its common ethic not to dry tool on established rock climbs. And when possible, climb in rockshoes to minimize any scarring.
Is it possible that someone down the road would want to establish a climb on the now scarred rock? Just asking!
This is a pretty stupid question.
You're asking folks to predict the future with certaintly.
Is it possible? Of course it's *possible*.
