The only way to opt out of Obamacare is via a hearse or election to Congress.
I don't believe that statement is true. Firstly, the Obama admin has given something in the neighborhood of 200 plus companies and unions the right to opt out. In addition, certain religious groups are exempt, such as the Amish. And in addition to those groups I believe reservation living Indians are also exempt as they're part of an autonomous "nation".
