A better analogy is phone numbers, where you can have a number that's not listed in the public registry.
But as long as the data is public, this is what you get, even though owners of private jets don't like it.
It does seem like there are some options for hiding ADS-B data.
But of course this could enable other tracking methods
I used to track planes around my house and I sometimes have seen some that were not broadcasting a signal... Maybe Elon needs to look into that.
