I don't know tobyhill, I hope he's rich, I'm sure he means what he says, etc., etc.
HOWEVER
Most who choose this path deal with the reality of medical bills they can't pay by - not paying them.
Since we require, by statute and by tort law, that hospitals and doctors deliver the care, no matter what, and since we allow nonpayment, we are on a path to destruction - slow but sure.
Something's gotta give.
I am not rich but I can afford to payout whatever bills come in. They may not get it all at once but they will get it.
