He would have to force them to do so, and also force state insurance regulators to go along with the idea. To be able to get people to enroll in their health plans, insurers have to offer competitive premiums and offer a pretty good provider network. To pull that off--to be able to price their policies competitively--insurers have to get hospitals and other health care providers to give them decent discounts. But if an insurer doesn't already have a lot of enrollees, health care providers have little if any incentive to offer it much of a discount. It is extremely difficult for a new entrant in any health insurance market to achieve sufficient market share to turn a profit.
