you fund it yourself. But you have the option because there are people who will take money to treat you.
In a pure government run system, paying for treatment yourself is not allowed.
That's why I said that government run systems only work when you have the option to not rely on them.
for all that people have been claiming that medical care in the US is a disgrace and behind the rest of the world, when people with money really need treatment, they come to the US to get it (except when the AMA has not blessed the treatment, then the people with money go where the AMA doesn't block new treatments)
This indicates that while the 'health care system' may not be what you want, the medical care available is what you want.
the problem is trying to find a way to solve the problems without loosing the advantages.
