>But this does not even compare to all the problems I've had where I've not been living in the same place stably for an extended period of time. It has been an absolute hell in some cases, because institutions (governments, banks, etc) simply do not account for this possibility. They all assume that you have a stable address of residence.

I haven't personally had this issue but I know someone who did in the US. No permanent address; they were doing a lot of traveling.

Nothing wrong/illegal about that. But, by the books, it means they can't get a driver's license and other important documents. So you basically have to lie. Either use a third-party digital nomad service (which I understand some states may flag) or find a trustworthy friend or relative to "live" with (who will forward important mail to you and vouch for you if needed--which is what they did). There are still potential issues with respect to things like jury duty but these can mostly work although they're almost certainly at least marginally fraudulent.
