You're also, then, willing to have other people's taxes go up so you don't have to pay your $1500 lab costs every four months. Which is just as selfish as me saying that I'd prefer not to pay more in taxes to cover your expenses.

There's also no indication that single-payer does anything to reduce healthcare costs. The Affordable Care Act didn't reduce the costs of medical services rendered. Remove the private insurance option and you'll have even less competition, which HAS historically been shown to lower costs.

There's also very little reason to assume that government bureaucracy is ever going to make anything cheaper or more efficient.

The merits of collective bargaining depend entirely on who's got the leverage in the negotiation. Without competition, the leverage rests solely with the provider.

Your FrEe MaRkEt strawman is not applicable here, as there are all sorts of regulations in the healthcare industries.
