Our Rights Cost Nothing

I'm making a spin off of an idea talked about here: http://think3institute.blogspot.com/2009/07/right-to-get-isnt-right-to-have.html

Our Constitution grants us opportunity. It never grants us the final result: achieving that is our responsibility.

Freedom of speech means we can not have the opportunity to speak taken away, but it does not mean everyone else has to listen by government mandate. The right to bear arms means I have the opportunity to own a gun, but it is not the government's responsibility to buy and distribute guns to everyone.

To those who say healthcare is a right show me where it is in the Constitution. To those who are still not deterred, considering the fact that by law no person can be turned away in an emergency room, how is the opportunity to be treated, to have health care, not here already? Using the Constitution's philosophy of rights without mandate (right to speak, not forced to speak, not forced to listen to others speak) why do you support the government providing health care insurance and mandating it?

I would like an answer.
