Think of it as robbing Peter to pay Paul. Paul gets a subsidy for health insurance. Peter pays by being charged higher premiums for his own insurance and by funding Medicaid with taxes or by lending to the government.
According to the Democrats and their friends in the media, if you stop paying Paul, then you are “taking away his health care,” and that is unacceptable. If the Republicans concede that, as they appear to be doing, then they are left with tinkering around the edges by shifting around the Peter burdens (probably by using more borrowing) and by cutting the subsidies for future Pauls.
The thing about health care is that it is so expensive nowadays that robbing Peter to pay Paul involves really big bucks. So if Obamacare has moved the Overton Window to the point where robbing Peter to pay Paul is entrenched policy, then the government now owns a much bigger chunk of the economy.
