You're correct on all those, but OP was talking about people who praise the Affordable Care Act but vote for politicians who say they want to get rid of Obamacare. Those people aren't using the system but want better, they are just ignorant that the two are the same thing.
Now we absolutely could do better, but it's better than what we had, and Republicans still want to get rid of it, even with less ties to Obama in name now. They truly hate people.
If I think cutting my brake lines will make my car go faster, I am, in fact, a moron directly failing to achieve my goal, NOT an intelligent being seeking alternative options...
Well, for almost a decade the GOP has had time to come up with their vision. They ran on "Repeal and Replace" in the 2016 cycle. But when it came time to vote to repeal, they still didn't have a replace option.
Prices didn't go down when the 2018 tax cuts reduced corporate tax by about 30%, I doubt when the ACA gets repealed and insurance companies can drop the uninsurable people they will lower the prices for healthy Americans, because they are already anchored at the higher price.
