If I'm reading this correctly I don't understand your logic. If the government is mandating insurance companies to cover people with existing conditions that means the government makes the decision and then dictates the terms to the insurance companies. Wouldn't it make more sense to have the government in control thereby skipping the "middle man"?
As for the costs of a universal plan let's look at the land size and population of a few countries.
Canada:........Land: 9976140 sq. km..................pop: 31,902,268
US................Land: 9629091 sq.km...................pop: 280,562,489
Australia:.......Land: 7686850 sq.km....................pop: 20,601,000
France:..........Land: 547030 sq.km....................pop: 59,765,983
Sweden:........Land: 449964 sq.km....................pop: 8,876,744
Germany:......Land: 357021 sq.km...................pop: 83,251,851
Norway:........Land: 324220 sq.km...................pop 4,525,116

Take Germany and Norway as examples. Roughly the same land mass but Germany has 18 times the population of Norway, yet, both countries have a universal medical plan.
Or compare Sweden and France. While France has approximately 20% more land it has 7 times as many people, yet, both countries have a medical plan.
Furthermore, those countries have pension plans and other social plans and their life expectancy rate is as high or higher than the US.
The cost factor is simply a scare tactic. Countries, large and small, sparsely or densely populated, can afford a universal plan. Furthermore, when was the last time you heard of a country dismantling their universal plan and returning to private medical care? To my knowledge it has never happened. Not once.
As I stated before this is not a journey into the unknown. Other countries, rich and poor, have done it. If left in the hands of private interests there will always be someone trying to squeeze a dollar out of ill people.
As for profit the entire country profits from healthier citizens. Healthy people are happier and more productive. And an extra benefit, although seldom mentioned, is healthy women look a lot better than ill ones.
