Trying to break the fundamental laws of physics is apparently where magical genies draw the line. The person wishes for protons to be heavier than neutrons, and suddenly there's a mysterious "fourth rule." Classic. If protons were heavier, they'd decay into neutrons, electrons would get gobbled up, and atoms as we know them would cease to exist. The universe would basically implode. But sure, let's pretend your wish to make your crush fall in love with you is the problematic one. Priorities, people!
