"Every system of providing care falls short of the goal of providing everybody with all the care they want at no cost to anybody."

That statement is both absurd and disingenuous. Nobody is expecting to have health care at no cost. What those of us who advocate for a single payer system do expect is that costs will be distributed equitably and paid for in taxes, exactly the way it happens in most of the world's advanced nations which provide universal health care coverage.  This is a no-brainer.
