If you think the government is going to take your guns, you should sell your guns

The first panel of this The Knight Life comic: "Whenever gun nuts think their weapons will get taken away, they buy tons more!!"

I have no idea whether people actually think this way, but, at the very least, it's a fairly common trope - the idea that American gun people think the government is going to take away their guns, and stockpile guns in response.

It occurred to me when I read this comic that stockpiling guns is the most foolish thing you can do if you fear the government is going to take your guns away.

On the day the government takes your guns away, they will take all your guns, no matter how many you have.  They wouldn't come to collect X number of guns from each person, they'd come for all the guns.  Regardless of how many guns you have at the beginning of Gun Confiscation Day, you will have zero guns at the end of the day.

Therefore, if you stockpile in advance of the government taking your guns away, you will still have zero guns at the end of Gun Confiscation Day, plus less money than you did before you started stockpiling.  Nothing is gained, guns and money are lost.

A better way to prepare for the government taking your guns away is to sell as many of your guns as possible before the government gets there. You will still have zero guns at the end of Gun Confiscation Day, but you will have more money than you did before.  Then, after the gun confiscation is complete, you can use that extra money to acquire more guns.

Some people might be concerned that it will be more difficult to acquire guns after Gun Confiscation Day. But stockpiling in advance won't negate that. If you stockpile, you'll come away with zero guns and less money. If you sell, you'll come away with zero guns and more money.  And it's always easier to acquire contraband with more money than with less money.
