Fair enough. My issue is that whenever you get super science or magic involved, there always seems to be a certain set of immutable, inarguable rules to a world up until the plot or the next writer decides to toss them out. It just seems so arbitrary. At least when you know Cap's going to face Thanos without Meow Meow he's going to lose (well, with Meow Meow, too, come to think of it).
