Someone mentioned in another thread that gun ownership should be like your citizenship: once renounced, you're back to square one in getting it again. This has gotten me thinking. What if there's a national FOID issued along with your passport, nationalization papers, or birth certificate? Think of it like an SSN card and a drivers license combined. This card by default grants you the ability to buy a gun. Once you pass a 4473, you automatically get that endorsement. The same applies to a Form 1, 4, etc. Prohibited life events like violent felony convictions would cause someone to forfeit this card. Or, if someone is so anti-gun, then the option to simply turn in the card is also available. Benefits: Since all citizens get one, the potential list of all gun owners is nearly every legal person. Criminals and those voluntarily giving up their rights are easily identified. Dealers can easily identify who they can legally sell to. Buyers undergo one background check for each type (suppressors, class 3, etc. being other types) of purchase, and because of the endorsement on their first purchase, they won't have to keep doing the paperwork the next time(s) they want to buy a gun. A one time tax stamp would be a side benefit. Can they come and take your guns based knowing you passed a 4473? Sure. But passing it once doesn't mean one purchase. I'm sure I'm missing a lot, but I'd figure I'd throw this out for public scrutiny.
