Most of what Jeff Jacoby is saying is a bunch of poppycock. It's not based on economic reality.
While I think getting the government out and letting free market loose in health care is a good thing, it's going to do very little to lower costs. Health care costs are high because treating someone with a chronic disease is expensive. Take Care clinics and the like can go a long way in reducing the costs for preventive care and some ambulatory care, but we already have those operating in the marketplace. We're getting sicker, older and fatter as a nation and treating the old, sick and obese and the diseases that result from those is not going to be done on the cheap, no matter who takes over.
