This is not inventing charges to jail people for not being "enthusiastic participants." If you don't comply with a law that makes it illegal to own a firearm, you're breaking the law. Breaking the law doesn't mean you're not being "an enthusiastic participant" - it means you're committing a (presumably) criminal violation.

Except that you have to *prove* I'm lying. It can't just be because Reasons.
You'd need to catch me in illegal possession of the weapon in question.

After that depends greatly on the circumstances of enforcement. Guns aren't like drugs or liquor. They are big, heavy, hard to conceal, are complicated to manufacture, and require supplies (ammo) to be functional. If we made a real effort to crack down on illegal gun ownership, you could probably get down to Japan/South Korea levels before too long. Certainly more than a few years, of course - but doable, eventually.

See my earlier point about Devil In The Details.
To do what you want, you're going to need to lock the border down. There is zero appetite among the crowd that wants to confiscate guns to do that. Ditto for port control. If you don't do either of those things, weapons still come in.
