The constitution does not declare one right that you have and doesn't even mention itself as a document of human rights. It does mention powers that the federal government has and those powers define the purpose of that government. Since the federal government has those powers it is reasonable to assume that it also has the right to execute those powers because you can't grant something powers and then deny them the right to execute those powers. The federal constitution not only defines its own powers but also makes it clear that any powers that is not defined in the constitution remains in the hands of the citizen. Those powers, whatever they may be, are not a creation of the government but are intrinsic to the individual. There is no action government needs to take for any person to have any power in their own life because any power we do have is the result of our existence within a society. Any ability you have (or power) also includes the the right to execute that power which is identical to the government's right to execute whatever power it has in the constitution. This is what a right really is; it is simply the right to execute a power that you possess such as the power to print newspaper articles (free press). This is a fundamental concept about rights that must be understood because not everyone has the same power to do something in their life but they retain the right to execute whatever powers they do have. This can range from the power to purchase adequite health insurance, to engage in trade, marry the person we want, live where we want, and etc. All of these things mentioned are examples of powers that we have and while not everyone has the same ability to obtain these things every person retains the right to execute what powers they are capable of executing in their own lives. So yes, not everyone has the power to obtain health insurance but those that do retains the right to execute that power. Not everyone has the power/ability to become a millionaire CEO but someone who does still retains the right to execute that power. The spirit of the constitution essentially is a document that separates powers between citizen and government and any power retained by either side also includes the right to execute that power as they see fit which is why freedom exist in our society.
