Counterpoint: increasing access to public restrooms results in unuseable public restrooms. As someone who (a) likes to 'hike' in-city but (b) has a small bladder, I rely on public restrooms on city trails, and in my admittedly small experience (Fort Worth and San José) they don't just become disgusting, but actively get vandalised within a very short time, after which repairs understandably take a very long time.

Somehow the ones in Ann Arbor and Chicago don't seem to get such harsh treatment. I'm not sure why; maybe those cities just budget a lot more for maintenance.
