I think half the problem lately is everyone knows what palytoxin is, and is super scared of it.
Heres the thing, its called PALYTOXIN not zoa toxin, there is a distinct difference. While you certanly can get palytoxin from certain zoas, no one knows what ones have it, and what ones don't.
I think most people don't know the difference between zoas or paly's, so the just stay away all together. The chances of getting palytoxin are pretty slim anyways unless your "cooking" some rock with them on it, or actively cutting them up without proper protection. It's a defense mechanism, so if they are not stressed to the point they feel they need to defend themselves, your fine.
I agree with the above though, everyone slaps a special name on it, and charges an arm and a leg. It's pure BS, kind of the like the current bounce mushroom craze. The same mushrooms you couldn't give away 2 or 3 years ago, now are going for 2 to 5k.
