There are still companies involved with "roads, electrical supply, water", even when they are part of the public infrastructure. It's not like there are no drug or medical companies in Switzerland.

The evidence doesn't need to be "super clear." The numbers are pretty solid that universal healthcare is more efficient than the current system the US has. That is, the US government spending alone, on a per capita and GDP basis, is higher than the combined public+private spending in most countries with universal health care. Yet the public+private funding in the US doesn't result in a higher quality of health care, by most measures.

Even sticking to the US, we can get an idea from Medicare and the VA system of the advantages to single payer systems.

Those comparison numbers don't exist for the proposals you mentioned, and there is no reason or experience to suggest they make sense in the current market. (But, consider France's Minitel in the 1980s, when it did make sense.)

Also, the failure costs in health care are much higher than the failure costs in choosing the wrong mobile OS. The worst case for the former is an nation-wide epidemic. The worst case for your company is ... you run out of money and need to get a job.
