The point of such an approach is to make it so prohibitively expensive for stores to do the checks or for potential buyers to pay for such checks that nobody can afford to sell or buy a gun legally. Sort of like raising the price of gasoline to $50/gal or making car insurance cost $50,000/yr... you haven't banned cars, but you've made it impossible for almost anyone to drive one. It's an end run around the Constitution. Meanwhile, the battered wife who fears for her life or the homeowner in a bad neighborhood will be disarmed and the criminals, by definition, will ignore all the gun laws and arm themselves on the black market.
The criminals won't need guns to be emboldened.

"Another thing that’s pretty clear from the social [00:24:00] science, and this is presented in my Supreme Court amicus brief for a large coalition of law enforcement organizations in the Heller case was study, after study, after study of both burglars who were in prison and even one study that managed to interview burglars in St. Louis who were out of prison and were active, successful, professional burglars. Is … The biggest part of their working day is observing the place they’re targeting and trying really hard to make sure there’s nobody [00:24:30] home when they go in, because if they do, there’s a high risk of getting shot. That is a … A burglar’s risk of getting shot is about equal to a burglar’s risk of going to prison. If you figure one is a deterrent, then probably the other equally-sized risk is also a deterrent.
The Centers for Disease Control, in the mid-1950’s, and they’re not known as one of the top pro-gun organizations out there, did a national study that estimated guns [00:25:00] are used defensively against burglars in the United States about 600,000 times a year. And again, the large majority of scenarios are not a shot being fired. It’s just eh display of the gun. The distinctive sound of a pump-action shotgun being racked to load the round makes the burglar decide to leave the scene.
You can contrast that with what goes on in Australia after they did their ban on defensive gun ownership. And England, and the Netherlands, and Ireland, and lots [00:25:30] and lots of other places where burglars deliberately come into occupied homes, and do so with impunity. And they do so because the occupied home is better for the burglar because you’ve got purses and wallets at home, where you can take cash, which has … You don’t have to sell at a discount the way you do with other goods that you’re fencing on the black market.
And we know they … Not the majority, but a significant minority of home [00:26:00] invasion burglaries when the occupants are present, leads to assault against the occupants. So, when you increase home invasion burglaries, when you … If you keep the number of burglaries constant, but you move more of them to becoming home invasions, you will be significantly raising the assault rate in the United States."
