What will you say if, and probably when, you’re found wrong — because an open enough system won’t want to tolerate the associated abuses?
It is futile to change or tinker with Obamacare, or think that Republicans can "run" it better.
If Obamacare is not fully repealed and the immediate transition made to a free-market system, there will be single-payer.
The Republicans want what their corporate sponsors want which is Single Payer so as to to get the financing of the shoulders of businesses and onto the taxpaying near minority of consumers. It also creates thousands more sinecures in the bureaucracy for the lobbyists to cycle through. I fear Single Payer will be followed by Guaranteed Annual Income which will reduce the real income of all who work while creating a fare larger dependent class that those still working will have to support. Most of the resources sucked out of the dwindling tax paying class will, of course, not go to the “poor” but for the lavish support of the Lords and Ladies of the Superstrate Ruling Class.
