It is different because you typically need to know the municipality I live in first.
Also the registration allows anyone to track me anytime I fly.
How would you feel if you had a public gps transponder on your car publicly showing who you, where you are, and where you live? Also what if you are required to plaster that registration number on the side of your vehicle in large letters that can be seen from a block away?
It’s a massive invasion of personal privacy.
Absolutely air traffic in the sky should be identified. There is no problem with that, but it’s the idea that it is too easy to find out everything about an aircraft owner by simply seeing the number on their tail.
The rich guys obfuscate that info with shell corps to own the aircraft.
Shouldn’t everyone have the right to the same level of privacy regardless of how much money they have?
