You go in to buy health insurance let's say. What's the insurance company going to say? Are you healthy? Do you smoke? Do you eat healthy? Do you exercise? What do you say? "Of course I'm healthy! Give me your cheapest coverage!" Are you seeing the problem? There's an information problem. Because insurance companies know you can lie and that it's impossible to know really if you'll get sick or not basic health insurance doesn't actually exist. Insurance companies charge premiums across the board to protect themselves against this. It also becomes lucrative to spend money finding ways to deny coverage pnce you've become sick or looking into reasons why you shouldn't have coverage at all. What you get is an obese health care administration jacking costs up further. And there's all the overlap with Medicare and Medicaid which is redundant. Mandatory one size fits all coverage eliminates these issues. It streamlines the administrative mess and avoids what's called a "market for lemons" issue. The example I like to use is Canada spends 8% of GDP to cover every person. The US spends the same just to cover people under Medicare and Medicaid. It's a fact that Americans spend from 2x to 3x as much for health coverage through insurance plans and tax dollars than other industrialized countries,

This. The more people covered by insurance the cheaper the insurance is. It is a similar situation to utilities. Nobody really thinks that you should have five different power companies with five separate power grids operating out of each city... it just wouldn't be efficient. The difference is that issue was settled long ago and people are fine with it now. Once universal health care becomes a thing people will forget about it.
