The idea that checking for a US ID could possibly stop actual foreign bad actors from using it is also farcical. Millions of stolen identity documents can be bought on the dark web for relatively cheap. North Koreans have been hiring real American citizens for years to infiltrate tons of US tech companies as employees.

And ya, it's pretty easy to hide your intent once you have access.

I think your really anchored on anyone successfully breaking restrictions means any restriction is impossible. So your starting from the position that if it is possible for any actor in the world to get past a restriction, then the whole restriction is a farce.

KYC for example does stop most money laundering and financial crime. The most resourced actors like governments/ cartels often find ways around and it is a game of cat and mouse. Normal citizens don't really stand a chance to get around most of them.

Like it feels like your logic is that we shouldn't do background checks for employment because North Korean spy agencies get past them sometimes?

Even that is overselling the effort. Last time I checked you could find IDs with a simple image search.
