If we're paying more for nurse salaries, hospital administration, insurance company bureaucracy, and ineffective procedures near end-of-life with low probability of success, it's unlikely the cost diff is mainly due to "subsidizing innovation."
By removing the for-profit system, you would actually be removing rampant rent-seeking on something that should be a human right.

A very strange example to select, considering it was first discovered by Canadians and the patent was later sold for $1. US citizens are certainly not "subsidizing" insulin elsewhere.

Of course, anyone can do a google search and find some opinion pieces confirming their world view, that doesn't make it true.
The post article in particular just looks at the total revenue and essentially says "look how big it is compared to other countries, we must be subsidizing them". But this just justifies the extreme profit-seeking already in the sector, it's not an argument that it's necessary for innovation.
Even your own source [1] contradicts the idea that high costs are inevitably caused by this subsidization:

IMO, if the US decided to actually help its citizens every country the average progressive considers "great at healthcare" would likely implode under the sudden increase in cost. The cost of medication alone would likely nearly bankrupt several governments. Imagine if the price of insulin, almost completely funded by US citizens paying absurd prices, went up to its US price.
Much like with defense, the US taxpayer is the hero of the rest of the world's healthcare. Without US tax cattle the rest of the world would not be as nice as it is. It's just like when prices go up at your favorite store due to theft. The US is punished by insurance companies because other countries refuse to pay more.
