Who is this "single" payer? Where does he get his money? Do I have to pay him anything to pay my bill?
You're jousting at windmills. Single payer also describes systems offered by socialist countries, social democrats, constitutional monarchies, republics, communism with chinese characteristics, limited capitalist democracies... https://en.wikipedia.org/wiki/Straw_man
That's because he doesn't understand the economics of the situation. He wants to simultaneously avoid the responsibility to pay for the debt accumulated by past generations of Americans yet also fail to pay for the future risks of his own health when he's older. This kind of short term vision destroys economies. Many young men only fend for themselves and feel invincible against things like health care problems, sudden black swan events in their life, or family responsibilities. It's not a realistic outlook.
You don't understand actuarial science. Your own personal experience is irrelevant; it's the pool of people you are in and there will be people just like you who get cancer or other unforeseen illnesses and need medical care. Just because you personally didn't experience it doesn't make it irrelevant. What you seem to want to do is roll the dice of your chances knowing if it doesn't work out the state won't let you die on them and they'll somehow make up for your recklessness at that point. How much money have you saved up personally to cover catastrophic illness or disability, and have you researched the real costs of your care in those cases ?
With regards to healthcare this is total bullshit - look at the data from socialist countries some have over half a century of national healthcare systems. Lower healthcare costs and healthier populations compared to US. Just stop electing stupid governments who are manipulated by US corporations... And who cares how the US or any other country was established. How's that relevant to today's challenges ?
If you want to gather like-minded people and do that yourselves, fine by me. You have every right to think this and do it. Where you and the other people that think like you get wrong is when you start to think that you have the right to force me to participate in this. Who are you or anybody else to say how I or the other guy should live our lives? How do you know my or his motivations if you have no idea who I am or who he is? What destroys economies is people letting governments take over it, always basing themselves on the same old mistake: judging policies from their intentions, rather than their results.
I think judging policies by results rather than intentions is exactly where the support for single-payer healthcare comes from (for example ACA is more popular than ever in the last 48 hours). In addition to me, there's at least one more libertarian on here making the pragmatic argument in spite of fundamental economic beliefs to the contrary. I suppose you believe police are a fundamental evil too? I think the counter argument here is, who are you to say how the other guy should die? Not particularly compelling as a rational, logical thought experiment, but compelling from a evidence based, comparative observation.
