Then how would You go about your private sale?
What if you had a relative that offered you a good deal on one of his firearms? You going to involve the Feds?

Nope, the background check should apply only when buying from some one who does not know the buyer personally.

Such as if I walk into a gun store to buy a gun, they should
be required to check me out.

If my brother-in-law wants to sell me a Glock, he knows me personally and he is taking the responsibility for the sale to a non-criminal. Therefor I agree with you no check is required.
