The only problem here is that you are pretty much wrong on all counts. Humans didn't evolve by sitting around in lovey-dovey quilt making sessions. They evolved by the ones who were better able to survive wiping out the ones who were not.
The problem is that the majority of the population are lazy gets who when given a choice between 1) work hard and earn something for yourself and 2) let your neighbour work hard and earn it for you, pick 2) every time. So you can prattle on as much as you like about collective endeavours, but that's not human nature. Come down from your ivory tower and smell the coffee. Most of the world is perfectly happy to let other people carry the load for them.
This is the crux of the issue. a) that somehow medical treatment is totally different than any other service/commodity (it's not) and b) that we should be force at gunpoint to pay for every unhealthy
clown on the planet because of their bad choices.
If i want a better house, I earn more money so I can buy it. Ditto with a car. Want a better education? Pay for it. That's how the world works.
As for the second point, all you need to do is work at the ER in a major hospital for a while to see what happen when you give people free medical care. All the welfare grabbing losers who are already sucking on the government teat like that was no tomorrow show up for the most trivial reasons you can imagine, just because it won't cost them anything. Things that any normal person would either self treat of see their doctor in the morning. I'm not kidding, I saw a guy arrive once in an ambulance because he ate something that gave him gas. Think of how many thousand dollars that cost the taxpayers.
Bringing computers into the home won't change either one, but may revitalize the corner saloon.
