We are back to the same failures as your last argument about needing id to purchase a gun. Perhaps you should spend more time thinking these things through.
What we're back to, is you relying on technicalities to get out of an argument. That's because it is all you have in these arguments.
You cannot get medicare without having a picture ID at some point. And you certainly cannot get treated by a doctor without a picture ID in 99.99999% of the cases (eliminating the possibility there is some witch doctor who accepts chicken bones for service).
