Health care isn't a natural resource floating around accessible to everyone -- it's not air, water, whatever. In order for someone to be provided health care, someone else has to do something -- there's a cost involved in that, either the time of the health care provider or money to compensate for that time.
The problem with "universal" health care is that people don't make that connection or understand the implication. It means the police-power of government, the government's unique power of acceptable lethal force, must be used to take from one citizen and give to another -- either by forcing the health-care provider to use his/her time or to take money from someone else to compensate.
I think I'm a generous person. My family gives quite a bit to charity -- more than Joe Biden does, despite the fact that he makes tens of times more than I do. I might donate to someone who needed an operation they couldn't afford or to an organization that provides health care to those who don't have insurance and can't afford it -- but I have a significant objection to the government using its power of lethal force to threaten me with imprisonment or death so they can take money I earned and plan to spend on my family for the benefit of others. That should be my decision.
