Contrarian argument regarding point 2:
I find it weird and misguided how people think that using coercion to force people into buying healthcare is somehow acceptable. To those that think it will make the cost of healthcare more expensive for the rest of us, I think that is a dubious assertion, in fact I think it will get much cheaper. The presumption that they are in contentious debate with is the necessity that different people have to get different tiers of service based on how much they pay.
It makes all the sense in the world when you compare it to any other business. You wouldn't expect for someone who paid $1M to get the same level of treatment as someone who paid $100.
People would buy insurance according to different tier levels of quality and risk profile, with their being astronomically high costs of insurance for old wealthy rich people, who in their desire to prolong life will incentivize creation of new modes of treatment to cure themselves (Which in the short run the development of which will help them, but in the long run, everyone, as after it gets discovered and scaled it will get cheaper).
People would also buy cheaper level of tiers, from which naturally the quality of treatment, and queues will get lower/longer.
You will also have people that don't buy insurance, and this should be their prerogative to do, as it would be the healthcare providers prerogative to decide whether to provide them with free treatment (they are not slaves, they are not obligated to provide a free service, and what makes the people that don't pay more important or a higher priority than those that willingly pay and fund these services).
I'm not saying that this is the BEST solution, I'm saying that this is BETTER than anything else proposed which leads to things like the "cobra effect" in which you make the initial problem way worse by the implemented solution, than by what it would have been without it.
