The law is basically written by the insurers, and favors them. It allows them to segregate people based on who they work for, etc.
In an ethical system, there would be just a single, non-segregated pool of people called a 'market', and anyone would be able to purchase any plan they want from that market, regardless of which state they lived in and regardless of who they did or did not work for.
Federal employees have such a system, and prior to obamacare, there was actually bipartisan agreement forming around enabling everyone to participate in that system. It's probably why obamacare was rushed through quickly by the insurance companies.
