This does present a tough civil liberties question. So perhaps we should offer this: enter yourself into a monitored quarantine facility for three weeks (and make it nice and cushy) OR if you refuse, then you will not be covered for any Ebola related illnesses, should they occur. You’re on your own for the $500K treatment fee. And you will only be treated after receipt of advanced payment. Probably no more cases of “Trust me, I’ll just monitor myself”. Problem solved.
Unless you're an illegal alien like the president! Then Come on in and steal as much as you can!
