apparition.  What is to stop someone from just learning it and doing 
it?  Obviously, it can be dangerous (splinching, etc) and they 
certainly cannot learn it at Hogwarts (at least on the grounds).

I think you're right; I'm not certain how the Ministry can monitor 
licensed versus unlicensed apparators.  I'm guessing it's kind of 
like unregistered anamagi: if you're caught, you're in trouble!  But 
only if you're caught....
