In the case of freeze distillation, the punishment would be for evasion of (Federal and state) excise taxes, along with distillation without the proper permits. If some law enforcement agency busted your freezer, they'd probably come up with some other violations on top of those obvious ones.

In reality, I think the likelihood of a "freezer bust" and consequent punishment is pretty low. Moonshine busts are generally carried out on the state level, and the typical charges are possession and transportation of untaxed spirits.
