Scout, you solve those problems with legislation - just like NICS. Government could always decide to do something bad but that's not a reason to resist sensible policy - a government that wants to ban guns will.
That's what .govs do. They do Bad. Look at (f)Great Britain and Australia. "Sensible Policy" is just a stepping stone. And since when is .gov compelled to follow it's own laws when they can change or ignore them at any time? Again, Illinois is an example. The law says we have to have a balanced budget by 1 June. We haven't even had a budget since 31 May 2014. The law has been broken, but there's no enforcement mechanism. Not one elected official is in jail or standing trial. It's a farce.
The constitution has never stood for the proposition that all encumbrances on the exercise of a right are prohibited.
"...shall not be infringed." Please explain what that means counselor.
For example, you can't just wave the cinstitution at a polling booth and demand to vote with no id.
You sure can in Illinois with our new same day registration and voting. You can register and vote (Same Day !!) by just showing a credit card with your name on it and an e-mail from any jamoke that says you live at X address. And tell me that isn't ripe for voter fraud. (Law passed by our supermajority Democrat House and Senate !!)
This would be a simple policy that could vastly improve the ease of you owning guns, and help stop nuts and criminals from getting them.
That's what was said about NFA '34, GCA '68, AWB '94, the Brady Bill/NICS and every other of the 20,000+ gun laws passed. Look at Chicago and tell me that Illinois' FOID Act is doing anything to stop or slow down the shootings and killings there. Because that Law is
EXACTLY what you are proposing. In Illinois you MUST have an FOID Card (Firearm Owners ID, can take up to 6 months to get one because reasons. Can be denied and you can't sue to find out why) issued by the Illinois State Police to possess or own or even purchase a Firearm and/or ammunition. And you still have to go through a ISP background check AND a waiting period (24 hours: long guns; 72 hours: hand guns) on firearm purchases.
What you are proposing
DOESN'T.*expletive deleted*ing.WORK.Chicago is the proof of failure of your policy.
