I think you underestimate how much money is absorbed by insurance companies, and the bureaucracies hospitals/doctors offices need to maintain to deal with all the different insurance companies.
I don't think so, I'm including those people in the 5 million that would lose their jobs or see pay cuts. They are exactly the ones who will fight to keep the system as it is.
We absolutely should get rid of those expenses, it will take quite a while, or be a significant disruption.
