I have bought a sub 25watt mini PC and have used something like StartOS to use the FTP over TOR. Plus you could run your own Private Nostr Relay, vaultwarden for password management, and a personal Comms server. You hook it up at a family member's house and put it in a closet with a big sticker that says "Before unplugging talk to nostr:npub1wnlu28xrq9gv77dkevck6ws4euej4v568rlvn66gf2c428tdrptqq3n3wr "
That's worked pretty well so far.
