sure u can do that. insurances and governments are more powerful, and have more levarage in negotiating the price. you can always have unregulated capitalism as in the US where hospitals charge u an arbitrary amount, and medicine can cost 10 times more than in europe.

one thing that u miss out is that as a young person you get a constant amount of income and have low medical bills. so you might think "why do i even have to pay for medical insurance" but in the end you are subsidizing the medical bills for old people who dont get an income. i assume you one day wish to become old as well hence i think you would not object when your old to have young people subsidize your medical bills to allow you afford to survive.

social democracy is not socialism. its just regulated capitalism. thats one thing a lot of americans get wrong. living in europe, you probably know that its not like living in venezuela.
