Medicare pays hospitals and Doctors about 80% of what private insurers pay. Would they survive if their revenues dropped by 20%? Many wouldn't. I've seen estimates that Medicare for all would cost between $2.5 and $3.5 trillion in addition to money already spent on Medicare and Medicaid. Let's say there will be some cost savings by having more younger, healthier people in the program and the cost is $2.0 trillion. That's still more than a 50% increase in total Federal expenditures. How do we raise that kind of money? If we can't do we cut services or ration care?
here's an opinion about Medicare for all:

Sure, that's the opinion from a libertarian view point, rife with assumptions. The author is adamantly opposed to government involvement in the health industry as a matter of ideologic principal, including the ACA.
What it comes down to this whether healthcare as a for-profit industry is a good idea. Libertarians are all in favor of it, progressives ( and even some conservatives) not. (The famed Mayo Clinic, for example is a nonprofit organization)
Certainly universal healthcare cannot be instituted overnight for nothing. But right now, Americans are paying trillions of dollars for healthcare, at a rate
nine times higher adjusted for inflation, than they were in 1960. We currently spend more on health care than any other developed country and receive considerably less.

Again, every other country has figured out how to provide universal healthcare without bankrupting their economy – only in the US, for some reason, is it considered impossible.
Can it be done without raising taxes? Obviously not. But with the average American currently spending around $10,000 a year on health care and insurance costs, one must consider how removing that expense would balance against a tax increase to fund universal coverage.
Starting from scratch, I would say that increasing taxes and changing the healthcare model would result in considerable savings – not to mention the lives that universal coverage would save. And the benefits of increased productivity created by a healthier population.
"We can't afford it" has got it backwards. We can't afford not to do it.
