If one were to read the Constitution one would realize that the Constitution does not grant anyone freedoms, liberties, or rights. The Constitution only protects freedoms, liberties, and rights from transgressions on part of the government. A right is something that is inherent to the individual, comes from that individual, and is maintained by the individual. You are born with such rights like the right to speak freely, the only thing that can be done to that right is to have it infringed. No one can grant a right to another, only limit or impede the exercise of that right.
Healthcare is a human invention that does not exist in the natural environment. Only through the work of others and through the taking of resources from one party and giving to another does healthcare exist. You cannot force someone to give effort and resources to another and call that a right. In the absence of human intervention the individual would live their lives and succumb to the natural forces which would act upon their bodies.
Do I think we should provide preventative care and basic primary care? Sure. Do I think that we can? Maybe. Do I think that healthcare is a basic human right? Absolutely not.
