They don't care, sadly.

Exactly my thoughts. How long is this bench that there are dinosaur spines right in the middle?

Could we maybe not call homeless people bums?

The Dinosaur People of Bukovina, I expect. Doesn't look like the right architecture for the Bird Folk of Patagonia.

It is, though they do have other issues, like getting blackout drunk after a brutal day at a soul-crushing job and sleeping it off in public, which is what this is designed to prevent.

The infrastructure isn't just hostile to homeless people, but also to skaters, someone running/biking past a little to close, children playing and even people scooting over a bit to make room.
It's kind of like the curb cut effect but for making things worse.
