When is limiting competition promoting competition?

I thought the public option in health insurance was supposed to encourage competition to drive down costs. But it seems there are limitations on the consumer. You and me. Check out page 16 of "America's Affordable Health Choices Act"

Basically, you can't change insurance after the law is enacted.

You can't seek private insurance if you quit a job to be self-employed. If you change jobs with employer provided insurance. If you have no insurance.

Well, except the public option is the the only option if you want or need to change insurance providers
