And if that apparatus was used to prosecute US citizens for non-major crimes with any frequency it would come under scrutiny very quickly and you'd have politicians jockeying to legislate it out of existence and take credit.

Even if you take the parallel construction angle, no politician except maybe a dinosaur that is super-secure in their position (on the federal level that would be people like Pelosi, Fienstien, etc.) is going to tolerate that because if the other side can prove you knew then you're not going to have a job after the next election.

Obviously we need to remain vigilant but there are existing feedback mechanisms that generally prevent wide spread abuse.

They are two different philosophies, and thinking about how they'll play off one another is kind of interesting.

The US philosophy is to do passive surveillance and assemble the pieces after the fact, rather than mandating ahead of time requirements. Which means that US-based services will continue to be unhindered by such requirements, appearing "anonymous" to the rest of the world.

As more people globally are turned off by ID requirements, if they're able to flee to US services, then they're actually walking into a more sophisticated passive surveillance flytrap. USG will have ever more surveillance over other countries, without even having to clandestinely place taps.

Close allies will be given access through FVEY and the like, making that relationship even more lopsided. But allies' domestic law enforcement won't be, so they'll still be clamoring for more simplistic mandates requiring ID, further driving the process.

Except the dragnet surveillers pretty much know what they're doing is illegal, or at least in a very gray area. And odds are they generally only try to deanonymize people they consider a significant national security risk (with some abuse exceptions, like LOVEINT).

This is codifying forced attribution for everyone into law.

There's a big legal difference between the government working to unmask anonymous users and making it illegal to try to be anonymous in the first place. The latter is probably brazenly unconstitutional while the former is at least a constitutional grey area.

Not American internet users, for the most part. Note that those are at least justified by being connected to foreign actors, and that some of those surveillance apparatus are illegal.

Which at least in principle are supposed to be used only in an accountable fashion under strict judicial supervision.

This is not generally the case in most parts of the US I've lived in either.

More importantly, it's purely a private business asking for your ID in this case, and only as an age check. In the vast majority of cases they don't record or really care about anything except your date of birth. No bar I've ever been to kept any kind of record that would have enabled them to tell the government that I had visited the establishment.

I seem to remember that in Europe its not unheard of for police to ask to see "papers please" and fancy that its often the darker citizens that get asked that.

Not that the UK and USA don't have some problems in that area

The ID is for age verification, not Name or any other details.

ID verification of age when buying alcohol is practiced by many countries, not just US.
