Personally, requiring a public address for amateur radio is a big problem and I'd argue needs to be changed.
It makes you a target for doxing and swatting, and causes an unending amount of spam mail that you can't unsubscribe from.
It made sense in the older days when people routinely mailed paper QSL cards. The FCC also relies on amateur radio operators to self-police each other, which is relatively unique as far as enforcement goes (see: ARRL official observers - but even in that case, if you do something sufficiently wrong then the FCC will get involved and could look up your address).
In the US the address you give the FCC when you apply for a ham license does not have to be the address of where you live. It just has to be an address where you receive mail. I used my PO box.
There was actually a situation where a person who was feeding the ADS-B Exchange network used their amateur radio callsign as their station ID, and another feeder looked up their info and called them to complain that their raspberry pi's clock was out of sync and screwing up the network.

On the other hand... QSL cards are pretty cool.
