Maybe you meant to be sarcastic but that’s a really weak answer. For years, we listened to how the Libertarians were the only consistent party because they had a defined rule for every situation. If nobody was harmed or coerced, it was okay.
Prostitution was okay.
Abortion was okay (as long as nobody asks the fetus if they are harmed).
Doing illegal drugs was okay.
So you need a far stronger reason that this idiot’s lewd dance was not “okay” by Libertarian standards.
