If we make Healthcare a community service would you then be able to regulate behavior? Could we make smoking illegal as a condition of that Healthcare? We have fire codes regulating buildings so they don't catch on fire right? I think that is part of our reluctance to do the whole single payer system. My rates being the same as an overweight, alcoholic, smoker who's life choices have made him extremely unhealthy is something people don't like.
I still think getting costs under control to where people could afford Healthcare without insurance would do more good than forcing everyone onto a government plan. And sure there needs to be a well run public option insurance for people who can't afford their medical care. But lower cost would make this easier to do as well.
