What about the tax aspect of it? Or do you simply pay tax as resident of the place you last properly lived?

Maybe this is a more relevant question for non-Americans, since most other countries don’t tax their citizens on their worldwide income. Eg UK definitely doesn’t. But often it requires the employer to be comfortable with the HR situation you put them in. Often easier to contract via a company (intermediary HR entity or your own).

Many people just keep "working" for wherever they "officially" live and stay on the down-low. You get a lot of cash/barter happening also, and try to stay out of the attention of the authorities.

Many places have tax treaties that allow you to pay taxes to your "home" nation (and/or state/province) as long as you don't stay there/away more than a certain number of days each year. That also assumes you have the right visa to work there legally, and I don't mean work for a local company... I mean do any work that you get paid for such as remote work.
