Edit: Let me also add this; when you sign up for health insurance you're entering into a contract with the insurer. They have to be up front about what they're providing and it's your obligation to understand what you're buying. With the government you don't get that. You get whatever the vanilla flavour of healthcare coverage is today. There's no contractual obligation, only whatever the government says is right today. You don't get a guarantee. Because there's no contract you can point to, even if you're legally allowed to sue (and I don't think you are.) you won't have a case to stand on.
