I'd argue it's more like KYC for the internet. Something HN users have brutally and ruthlessly defended for banking every time I argue it's a 4A violation (in fact, it's one of the most fiercely defended things anytime I bring it up).
Give in 20+ years and you'll be called a kook for thinking otherwise.
Can you explain the connection between KYC in banking and the Fourth Amendment? How does KYC constitute a government search/seizure?
KYC is one of the greatest government overreaches in the last several decades. I'll back you up on that.
