As a socialist libertarian that access health care, yes I think is a great step forward, I see all this social services that benefit the proletariat given by a government as positive part of the transition, but it's also a double edge sword if people become too dependent or get use to it once stops been an urgent matter people stop demanding it because they forget that's even there and end up voting for politician that would take it away, I'm thinking about Sweden or the uk. The correct way is demand these services to become more decentralized, f.e. having fully equipied clinics everywhere instead of just big hospitals

I'm not a libertarian, but from what I've seen of their positions on this, they don't think that it's possible in an effective way. There's two possible versions: the government pays for everything, or there's public and private health care. A lot of countries have both, which is probably the best option since driving out competition is going to make everything go to crap.

The problem is that there are some arrangements that simply can't work or the existing system would implode in the transition.

There are also a lot of people who don't want to pay because someone who refused to get insurance for years finally decided to sign up for public health care because they suddenly got a serious health problem. In some possible arrangements, it would be necessary to force people to have health insurance, which is its own rabbit hole.
