What I'm suggesting is food stamps. Everybody can pay cash. If you can't, you get government assistance in the form of a cash-like subsidy that can be spent anywhere food is sold.
It's a fast, efficient way of ensuring universality of care while benefiting from the market discipline you get from having a (mostly) competitive, cash market. Not to mention, there is no insane "food insurance" bureaucracy. You swipe the card at the checkout line and you're good.
I was one of the people who lost insurance starting a new business - too rich to get subsidized (cutoff was/is >~50k/yr), too poor to pay the equivalent of a second mortgage for individual insurance because of runaway premiums on individual market post-ACA. And penalized a few grand for it come tax season until the mandate was effectively rolled back. Was more than supportive of that rollback.
It’s a risk management game for new business owners, and a big incentive for people to keep working for the man.
Also coverage is also a huge deal in the US, although it may not be a problem for you specifically. Obamacare covered millions who otherwise might have stayed home instead of seeing the doctor.
The problem with US health is scoping. Insurance companies are effectively “certifying” which hospitals and doctors you can see instead of actual certification bodies.
