That counts as many states, and most of the "anti-gun" states, which is what the parent actually said.

Personally, I think people should be as free as possible to sell goods privately without the government getting involved. It's not a loophole, it's how things should work.

If you think any of these laws prevent felons and other prohibited persons from getting guns, you must be remarkably unfamiliar with felons, and their willingness to commit felonies. Most felons I know through friends/family have a gun (often stored somewhere plausibly deniable), and it's not a particular secret.

These laws primarily harm law-abiding citizens — who were never the problem in the first place — far more than they restrict prohibited persons from acquiring guns.

The same thing will occur with restrictions on open models, but arguably the results are far more harmful — limiting the technological and economic capacity of the people and countries we have to worry about the least, leaving the playing field open for those we have to worry about the most.
