This is kind of like saying there is a checkout stand at the store for legal buyers, but there’s no place where shoplifters can pay for the stuff they take.
It’s a good analogy, the USA is a supermarket without a back wall, so to speak.
We would have to seal off our borders completely and patrol them aggressively. And register and track everyone who enters through the legal checkpoints. That is an expensive proposition, and means a lot more government bureaucracy.
