Have you looked at these new regulations, this is not a "gun show loophole" this is end private sales of guns, to prove the point read through these requirements and substitute the word car for gun. If you sell a "car" for more than you paid for it, you are seeking a profit, and are a "car" dealer, oh, so just become a dealer, not so fast, they fought that war 30 years ago when they killed off the "kitchen table" gun dealers, requiring dealers to have dedicated shop space open to the public, etc.
There is no gun show loophole, it is just another public relations tool used to cover up what they are really after, anyone that goes to a gun show in the last 20+ years knows that they are full licensed dealers who run background checks on every sale. While it might be possible for 2 individuals to meet up there, get to talking, and agree to a private party sale of a gun, the same can be done at any other locations, this is not gun show specific, this is the definition of a private party sale. Some years ago, I sold a gun to a coworker for a profit (I had inherited the gun, along with some others, so any amount of money would have been a profit), should this make me a "gun dealer"? Imagine the same sentence with "car" should someone selling a car they inherited to another private party suddenly become a "car dealer" just because they made a profit, how about a collector, how many car collectors intend to sell cars for more than they paid for them?
