My driver's license should have some anti-tamper identity proof that can do a challenge response. Or let me go pay a few bucks for an identity proof at the post office.

There must be a dozen other ways smarter people can think of but identity verification kills profits so the smart people don't work on them IMO. It's more profitable for social media to be an astroturfed shithole. It's more profitable to remove control of your PC.

Social media in an ad economy serves two masters.

End users should be authenticated so you can prove you're selling real eyeballs in the demographic mix you claimed to marketers and to provide lip service for the 'think of the children' regulators.

But anyone who's paying for ads should have as little friction as possible to dropping money and spewing garbage.

I'm surprised nobody is looking at some sort of "corporations are people" angle here-- we've attested the device ownership, but it's owned by the Lorem Ipsum Corporation, which is a legal/demographic dead end and spawned just long enough to buy the device.
