There are some exceptions, including for hobbyists who are selling firearms from their collection and people who sell firearms they inherited.

This makes the law toothless. People who were selling mainly for a profit just at gun shows were already in violation of the law, just that nobody did anything about it.

Now they’ll just claim to be hobbyists and can continue as if nothing changed.

The only way they can make this stick is if they determine that “for profit” means you make more money than you bought it for, rather than intending to make more money that you bought it for, which would be ridiculous.
