In a perfect world, we would not need insurance companies. But I have never had a problem with the way things always were all of my adult life - at least until my premiums and deductibles started shooting up under the ACA.
I always liked the old system - I either got insurance through a job or have bought it on my own. I paid my premiums that were based upon my own individual profile and flashed my insurance card when I went to the doctor for whatever reason. Never have had to wait very long to see a doc or get any treatment. Have always been able to go right over to the pharmacy with any prescriptions, flash my card, and get whatever meds I needed within 1-2 hours or so at the most.
Let those who are un-insurable or unable to afford insurance continue to be "helped" by govt - work on the much needed improvements to that system. Leave the rest of us the hell alone - if it wasn't broke, no one had any business trying to "fix" it.
If I ever have to put my life and health into the hands of some un-elected DC govt bureaucrat, I'll take my assets, skills, etc and move elsewhere.
The reason insurance companies have had a hard time profiting under the ACA is because they were forced to insure the un-insurable.
The government doesn't do anything "simply", unfortunately. Of course who among us who are business owners and / or investors in other businesses wouldn't like to see our companies be bought out for FAR more than our businesses are worth by a govt that loves to spend too much - too much of our tax dollars, unfortunately.
Why stop with insurance companies? Why shouldn't the government buy out ALL US private industry, or as much as they can? They know better than we do, and can take care of everything for us, right? Maybe I also need DC hacks for what used to be taken care of by my auto, life, longterm care, and homeowners insurance companies.
Why not do away with private investment advisory and brokerage services? Much of the left knows better than me that US treasury bonds are the only investment anyone needs - no matter how many years from retirement one is, no matter their own individual risk tolerance, etc.
Since diet is a very important part of one's health, should the govt also buy up the fast food and grocery industries? Should our diets be controlled, rationed, and otherwise micromanaged the way Mrs Obama did with school kids for years?
Why not the retail industries? So many of them are getting crushed by Amazon that many of them are going bankrupt. Oil and gas? Housing? Auto again? Where should it end? Is there anything we should be allowed to do for ourselves?
With 20 trillion in debt, hundreds of trillions in unfunded liabilities, a debt to GDP over 100%, sluggish economic growth, etc, I'm afraid the govt is not in any position to keep borrowing and spending like a piss-poor 3rd world Latin American nation.
