> What is a "cave" and why would anybody even want one?

It's basically a space with a door that's dedicated to one of the inhabitants and their interests.

Even the closest of couples needs their own space occasionally, and having a "man cave" or "she shed" (yes, sadly they're needlessly gendered) provides that environment. They can also frequently double as a WFH office.

> apartments with multiple rooms are not difficult to p in cities lol

Sure, but at what cost? How much does a 4 bedroom apartment cost in most cities? $4k a month?
