I'd wager that the HN demographic skews just as wealthy as the hobbyist GA community. Indeed, your friend or coworker with a brand new Model X is probably wealthier than the person taking the occasional weekend flight in their used Piper Cherokee.

I think this situation is closer to corporations and other companies having to list an address in a public catalog. Anyone can start a business, even my neighbors. It's much cheaper than buying an airplane. But we've decided it's in the public interest to have that information available.

Small aircraft can be surprisingly affordable; many small used GA aircraft cost about the same as a nice car does new and they generally don't depreciate very quickly -- there are lots of perfectly safe small aircraft from the 1960s and 70s still flying.

You'd be surprised how many middle and upper middle class americans fly.
