I mean, looking at this from a logical perspective: if I had Galaxy level Attack Potency via something like creation, that should mean I can deal Galaxy level damage via means like creating something like energy beams or whatnot with the same potency, right? And if said characters can withstand it, then they by definition should have Galaxy level durability, no? You do realize that just because someone has a certain level of damage they can inflict on others like Country level via a calculation doesn't mean that they can actually destroy a country, right? Donkey Kong may have Island level AP due to his moon punching feat, but that doesn't mean he can destroy an island with a single punch. And it's not like he actually destroyed the moon, anyway; he only knocked it out of orbit.
