No one said ACA was perfect, it was not. It was the first step to single payer, that was the hope of the right. Those same people thought that when the problems were found, solutions would be given to change the system to improve it. The Republicans would never do that, no matte how much the Dems wanted to change and improve the system. Look at the original bill, money was in it to provide costs to the insurance companies to make up for adding the people that preexisting conditions. The Rep. axed that money, making sure that the insurance companies would never be able to recoup their costs by offering insurance to these people. ACA is like SS, the right hated it from the start, and wanted to destroy it from its inception. They realized, correctly, that if was successful, people would like it, much like SS, and it would turn into a single payer program. The big money that insurance companies, big meds, ect will be gone. That is why they want to destroy it, and give us the unfree market. Selling insurance over state lines will not fix the problems. Just keep the profits rolling in, is the only thing that matters.
