Closing bigger public bathrooms and switching to individually lockable bathrooms - cells, basically, often with codes if at a business did work. It filters out

Closing bigger public bathrooms and switching to individually lockable bathrooms - cells, basically, often with codes if at a business did work. It filters out that bottom 10% that can't coherently speak or present themselves to pass a vibe check in asking for bathroom access. Things did improve for those with standards, at the cost of having to deal with the bathroom equivalent of barbed wire topped walls around your home compound. That IS better than walking in on the bottom 10% or the disasters they create, but only slightly. Collectively, squeezing the bottom out by denying them access building by building, block by block has helped turn parts of cities around. It's not that different than locking up your food high in the air when camping so animals don't get into it - they don't come around and stop coming around if they are.
