Because these things are abused. Simply providing them doesn't solve the problem--we'll just have really disgusting facilities that few people, if anybody, uses. I don't know how to solve the problem. But railing against the symptoms doesn't help. Filthy public spaces are worse than no public spaces, and no public spaces is precisely what we'll get if we try to address the symptoms without addressing the underlying causes. Parks disappear, buildings are built without public spaces entirely or with "public spaces" inside buildings where security patrol and which become inaccessible after hours, etc.
