Oh, I agree it won’t be easy, particularly when taking profits from rich people.

I’ve heard it likened to a house full of asbestos. Knock it all down and there’s likely to be collateral damage, but meticulously taking it apart will take a considerable amount of time. I feel it would be easiest for governments to purchase the insurance companies, then slowly amalgamate so it’s all one network open to everyone.

Also it’s a bit entertaining when someone opposes it because “it’s socialism”. It’s already socialism, you just have middlemen skimming profit off the top while providing little value.
