Most of those “no loitering” signs only exist to give the police a legal crowbar against homeless people. Realistically if you’re just sitting and minding your business nobody will actually come along and eject you.

I once went to a park sat on a bench and right in front of me was a no loitering sign. It’s a park, what else am I going to do?

That is hilarious (well, sad actually, but you get what I mean). Also kind of reminds of that one politician once saying that “breast are not suitable for small children” in the public breastfeeding debate …
