How does one lead to the other? Social safety nets are not mutually exclusive with removing a lot of other market barriers. See my prior comment on this thread -- our healthcare market is the most distorted in the world (even when compared to 'universal healthcare' countries). Freer market means 'easily treatable' conditions are cheap, as opposed to our current system where they are expensed behind oppressively occupationally licensed practitioners selling monopolized medical products, where a 10 minute checkup with a dermatologist out-of-pocket is nearly $500. But regardless, it is certainly an interesting, quantifiable argument (albeit hypothetical) that a 20% speed increase medical innovation in a free market could be measured against lives saved with today's medicine in a socialized system, assuming that system makes services as affordable/accessible as intended.

Here's the reason health insurance as an industry can be considered fraudulent, especially when it's generally the gateway to all healthcare access -- and why ACA fails to fix it. Pre-existing conditions and re-adjusted contract rates.

If there was one company and one client, they could certainly craft a perfectly sound insurance contract to pay a set rate with steady increases over X years in exchange for coverage in the event of future, currently unascertainable medical services. But if you are responsible and get insurance BEFORE you get sick (by the way, not much sympathy for those who do not and demand that insurers take them, since that's the whole point of insurance), you are effectively tied to this contract and can never again negotiate another of equal value after you have been diagnosed with a condition, even though your initial/current contract already priced in the risk of getting those conditions. In fact, the rates to cover your risk, which need to be higher on average than the amount of healthcare you actually use, become ridiculous quite quickly. This problem is amplified by the fact that the government thought it was a good idea to tie healthcare to employers, so people switch very frequently and therefore are forced to renegotiate contracts frequently, robbing them of lost value that would be acquired if they were able to ride out the original contract.

So to say health insurance is inherently fraudulent is hyperbole, but in the current setup, it functionally is, because it is non-transferrable. ACA attempts to address this problem by subsidizing those who do not make much money and forces insurers to take everyone, but this just adds artificial demand (due to the subsidies especially) up to the amount of the maximum subsidy and raises everyone's rates (although those who are subsidized will see somewhat lower rates), and does nothing to address risk renegotiation, especially since it includes people who never had a contract. Similar economic effect as student loans/student aid. Each dollar increase in student aid raises tuition by over 40 cents... the rest is probably distributed across student housing, amenities, textbook prices, concert prices in college towns, etc.

A better way to eliminate the fraud, while still limiting ourselves to an insurance-dominated system, would be to legally codify standards for contract negotiations, which would allow contracts to be traded/transferred between companies, effectively locking in your risk at the time you first get uninterrupted insurance (and perhaps some protections for temporary uninsured periods).
