But, I also believe that new people coming into that kind of environment should be allowed to. People step on each other's toes, and it can be annoying. But I still don't believe that people have the right to keep other people out.

They generally are. But it's not practical to enforce them in a condition of a lot of short-term rentals, where people rotate on a weekly basis. Before AirBnB, that might not have been a problem, but now that's trivially easy to become a pirate hotel anywhere in the world, people are pushing to ban such rentals in residential areas, because it's the only way to make the problem go away.

That's another negative side effect right here. Occasional vacation sublet by a thoughtful homeowner doesn't hurt anybody. But those cases become collateral damage of the effort to fight off AirBnB's pirate hotels.

You could be right. I would like to think that there is some option which would make everyone more-or-less happy, but it could be that I'm being too optimistic.

My neighbours are much more careful at 4am, and each might only leave like this a couple of times a year. An apartment on AirBnB has this pretty much every week.

You don't of course. Anyone shouting at 4am is being exceedingly rude; if there's any social contract in place, then they certainly aren't honoring their end of it.

Under these circumstances, I certainly wouldn't blame you for advocating to your municipal government that they crack down on AirBnBs. I would just hope that that government try to find some way to simultaneously keep the needs of visitors in mind. Maybe there is not a true win-win scenario here, but the status quo doesn't seem to be working well for anyone.
