Well, you can buy partly subsidized or receive fully subsidized healthcare (ACA/Medicaid). That's on top of programs like COBRA and in worst case scenarios welfare from the state, county, or federal levels. We also have CHIP on the federal level which is a separate program just for children, where the parents may have insurance but for some reason cannot insure their kids. That's on top of what the states themselves offer, but that's sort of rolled into the ACA nowadays, which makes more sense.

We're at 8% uninsured, which is nothing to brag about, but its far from a free for all post-apocalypse where people keel over in their desks or in the unemployment line. Its also important to note that those numbers include illegals who can't or won't get insurance due to citizen status and 1/3rd to 2/3rd of that number actually qualify for various insurance programs, but for some reason aren't seeking it (aside from citizen status).

We absolutely have a big problem with the rural poor and insurance, which is a hefty 14-20% of that demographic. I'm not sure what the fix here is especially considering rural states are heavily conservative and fight off ACA and Medicare/Medicaid expansion regularly.
