Because it is entirely understandable that magic plays by different rules- that it does so is self-evident- and its damn difficult to understand how the universe is telling me that I can't swing my arm just so without actually being in some kind of physical restraint. Nothing in reality suggests such a model.
I may be restrained or I may be too tired to do so, but that isn't what the 4Ed mechanics are saying. They're saying that you cannot do a maneuver for the mere reason that arbitrary game balance mechanics dictated that it be so.
