The Simple Solution

Why don't we look at healthcare like we look at driving insurance?
Just require all adults to purchase health insurance like all drivers must have car insurance.

Let the states define what "minimum coverage" is, and focus the rest of your energy on legislation to reign in the exorbitant fees doctors, hospitals, health equipment manufacturers, and pharm companies charge.  Really, this is the problem with healthcare now, not the lack of universal coverage.

If u can't afford car insurance, you can simply elect not to drive and just walk/bike/pubtransit, etc.

If u can't afford health insurance, what does your plan leave you?
