The main con that comes with the double-edged sword of remote work is isolation from in-person human contact. You can socialize just fine, to an extent, through applications like Slack, but there's also something to be said for having some in-person socialization throughout the day. Therefore shared workspaces and things like that have a solid purpose.
However whereas shared workspaces can be expensive, public libraries are free. So assuming someone just needs their laptop to work, and not two huge monitors or anything else like that - assuming they can just throw everything in a normal-sized laptop bag - what's stopping them from using the public library 8 hours a day, 5 days a week indefinitely?
(Just to be clear, I'm not talking about chatting with people throughout the day. It's just the idea of having other people in close proximity, as an ambient aspect, and that sort of thing in general. Occasionally having someone to nod to while walking by and that kind of thing. The thing that's being avoided is being completely alone inside one's apartment all day or something.)
Libraries will often have free wi-fi, a free place to charge the laptop, free everything except coffee. And if it's just the occasional person doing this, they probably won't mind. However, especially considering the work-from-home situation with COVID-19, what's stopping these places from being swarmed and overcrowded indefinitely with people of this nature?
In particular, in a typical US municipality, what legal setup blocks public libraries from being swarmed by people using them indefinitely as free work offices? What are the normal legal limits that allow libraries to get used like this in moderation, while preventing them from getting overrun?
FWIW, the main reason this has come to my mind is that, for certain reasons, I've been spending a few weeks on the other side of the US from where I live. During this time, I've found working inside the local library to be usually fairly preferable to working inside the hotel/hostel. So much so, that it's tempting to keep doing this once I'm back home next week, and I'm wondering how much is too much, and how that's reflected in a typical legal setup.

The important thing here is that I am not talking about breaking any rules. The second the library tells me to pack up the computer, I will. However no such limit has been imposed for several days, and they've actually acted fairly friendly and accommodating up to this point.
Therefore, is there anything in the law (in a typical setup) that places a major limit on this type of usage? If it is nothing more than just simply waiting until the library staff say something, then that answers the question. I just want to make sure there's nothing in a typical legal setup that places a meaningful limit on this.
