I'm not completely 100% opposed to magical physics, though in IMO current physics is magical enough. However *if* physics continues to become more and more complex and/or magical it is going to start to push me into the "we have to be running on a simulation" camp. And I really don't want to go there.
My primary reason for pounding the doorstop under the door on magical physics is to try and force people to explain things using "conventional physics" before they resort to inventing things like MACHO particles and the like. We have far to many theoretical physicists and far to few astroengineers when we would probably be better off with things the other way around.
