Every address you've ever officially used follows you forever. So it's not so much that not having a fixed address is illegal, it's illegal to erase or hide your residency history entirely. I still have mail that goes to relatives houses in states I haven't lived in over a decade, and there are mail-in ballots addressed to dead relatives being shipped to their previous residences as well. As an aside, if anyone still has faith in this electoral system, or any institution in America for that matter, I don't think they're adequately prepared for the Kafkaesque chaos that's about to become commonplace, if it hasn't already.
