As much as I say fuck the billionaires, they have actually already had methods of doing this for about 50 years. Only the dumb billionaires who registered the planes in their name were annoyed about the rules. They could have always registered it under a trust, like almost every other rich person private jet out there. People can still figure out the plane tail registration and track you through that, and that will never change. So the billionaires that are happy about this regulation change still have their tail numbers known by the public to be associated with them and can still be tracked. Now they just have to change their tail numbers (giant pain) and wait for people to do slightly more difficult digging to figure out what plane is theirs.
