We're not forced by law to engage in any of our other rights. In fact, some of our rights are heavily regulated and restricted in spite of rather clear wording in the Constitution (ie "shall not be infringed").
Freedom of religion, freedom of the press, freedom of association--there aren't any laws which force us to avail ourselves of them. You don't have to express your opinions if you don't want to. You don't have to own a gun (in fact most of the government wishes you wouldn't). You don't have to demand to see a search warrant when the cops want to search your house; you can choose not to "remain silent"; you can waive any of your rights.
Yet, when it comes to this new "right", this one has the government fining us if we don't avail ourselves of it. Only a select few are allowed to waive their "right" to ObamaCare; the rest of us will have it whether we want it or not...and we'll pay fines if we don't, and go to jail if the fines aren't paid.
The fact is, it's not a "right" if government makes you do it. If government has to force you to do it, it is in fact a tax, a fee, a requirement, a burden, anything but a right.
There is nothing liberating about ObamaCare, nothing which will enhance our freedom or prosperity. It is more taxation, more regulation, more intrusion, and more control the federal government will have over us.
That's why they have to force us into it.
