Yes, even Ralph Nader gets it. I am also certain that one Donald Trump got it decades ago. The problem is not that we do not know how to do it it is that the insurance industry is prepared to pay and pay to prevent it. That is why the GOP effort had to go out and crash and burn in order to clear the road ahead.
The insurance companies simply cannot compete with it been done right so they have to be destroyed. Now we will go through the collapse of Obama Care and its Democrat supporters all shilling for the insurance industry.
All that sets us up for a national system modeled after the Canadian solution and also using the states to administer the whole thing. In Canada the federal government thinks about it all about once every decade and uses it to beat up the provinces as senior whiner.
