And yet, getting frisky (with yourself or others) on a nude beach is typically illegal.

Topfreedom, in places where that is legal, is also seen quite differently than full nudity. Going to a nude beach is an opt-in experience; consent to view fully nude people is implicit in going there. Where nude beaches are uncommon, they are typically very well marked as such.

And, to pick a nit, because I live in a locale where toplessness is equal-opportunity: we enjoy this freedom due to the lack of a law restricting it.
