There's plenty of wacky. But until the country is rebuilt theres no way to enforce them. you need a basis that can build on.

I prefaced the question by saying you had unlimited Legislative/Executive/Judicial power, you can enforce anything in this situation.

Besides, most wacky would border on degenerate, anyway

What wacky law where you thinking of that would border on degenerate?

Given the fact that the US is already almost impossible to invade, even from both sides, I would conquer both Canada and Mexico. All citizens would be exterminated. We would use nuclear weapons to separate the panama ithmus. Once sealed, we would fortify borders.

Once that's done, we tell the world in very kind words to fuck right off and begin to purge the undesirable from our own society that remains. Mentally ill. Homosexual. Part Jewish going back 5 generations. Using the snowy fuck of northern Canada as a prison.

I could go further. Much, much further.
