I'm not a Libertarian, but I sympathize with some of their economic viewpoints -- significantly more so than tends to be welcome here. Unlike some of you, I don't speak to the motives and attitudes of all libertarians, only my own. I'm not a Republican. I don't smoke pot. I did vote for Jo Jorgensen in 2020. I do give a flying fuck about liberty. I don't confirm or deny being a myopic cunt.
Oddly enough, I do support some form of public healthcare. I'm well aware that most libertarians don't. A hundred years ago, maybe even 50 years ago, I wouldn't have either. The problem is that medical science has advanced to where a free market insurance model doesn't work as well as it used to. Health insurance used to be a luxury when lung cancer would kill a rich man almost as quickly as it killed a poor man. That's no longer the case, and the costs have accelerated to where the treatment can bankrupt an uninsured middle class man.
The real sinker however is pre-existing conditions. You can't insure a house that's already on fire, and we don't ask homeowners policies to do so. Waiting periods for costly conditions sometimes almost work, except for patients born a pre-existing medical condition. If the insurer had the choice, they'd just refuse to write the policy, even if treatment is cost-effective from a public policy standpoint.
So I support free market solutions where they exist. Health insurance may be one of the few situations where it doesn't.
