I don't disagree with anything you said, but the simple answer to your question is that most American households are happy with their current health insurance and don't want it to change, so we keep patching the current (severely flawed) system as "needed" rather than starting over with a new one or making what would be seen as radical changes.
That poll doesn't say they're happy with their health insurance, it says they're at least somewhat satisfied with the coverage. You'd see very different results if you asked about health insurance prices.
I believe most people would incorporate the value received into their satisfaction rating.
Most people also don't have any idea how much their insurance costs in total or how it compares to alternatives, so that would be a challenging question to write with any reasonable expectation of getting a coherent response.
> The problem is the cost.
You could say this about almost anything that isn't free, and could still say it about a number of things even if they were free.
Feel free to look at the many, many, many alternative polls over the years. This is well known to anyone who has done any research into the topic at all.
Take the poll in 2026 after ACA subsides evaporate and Medicaid cuts. Highest satisfaction is for government run insurance (Medicare, Medicaid, Tricare).
https://www.nbcnews.com/politics/politics-news/poll-are-sati... ("Overall, 82% of Americans said they’re satisfied with their health care coverage, including a third who said they are very satisfied with their current coverage. The group that reported being the most satisfied were older adults, with 9 in 10 Americans over 65 years old saying they were satisfied. And 42% in that age group reported being “very satisfied.”. Roughly 9 in 10 of those who have public health insurance coverage through Medicare or Medicaid also reported being satisfied with coverage, compared to 77% of those with private health care coverage.")
https://www.citizen.org/article/public-support-for-medicare-... ("Support for Medicare-for-All continues to rise, whether in Congress, state legislatures, or among the American people. Recent polls indicate that six in ten Americans support Medicare-for-All. In addition, more than 60 percent believe that government is responsible for ensuring health coverage for all Americans. And nearly 70 percent of all voters, including battleground voters, identify health care as an important issue in upcoming elections.")
Yes, it's noted in the poll I linked (which is the same one as your first link) that the highest satisfaction is with government run insurance.
Not enough people are on ACA with subsidies to move the poll results that much, and Medicaid cuts aren't going to make people less satisfied with their private insurance.
I have no idea why you and so many other people seem to be taking my explanation as to why the US doesn't adopt universal socialized medicine as some sort of endorsement of the status quo.

For the kneejerk downvoters who seem very confused, this was released yesterday: https://thehill.com/policy/healthcare/5650010-survey-aca-cov...
This has been an issue for decades now, with countless polls to back it up.
