I think it falls under basic "liberty". Humans have always extended our natural abilities through clothing and tools. Because of this, we can survive almost anywhere on Earth and recently even in space. People have been artificially enhancing their appearance throughout recorded history.

As for altering the body's intrinsic ability through medicine, this is not a recent thing either. Drugs have been around throughout recorded history, enhancing religion, health, comfort, and social relations beyond what staple food provides.

I see it more than a right. I see it as a necessity for survival. Societies that are more restrictive will find themselves unable to compete with others who have made themselves better in business and war.

I see it as a way of efficiency. Imagine the energy savings if people could grow fur in the winter and shed it in the summer.

I see it as the path to oceanic colonization. Imagine how hard it would be to build a city underwater. Now imagine how much easier if people could grow gills.

I see it as a path to interstellar colonization. Imagine how hard it would be to establish a colony of spacesuit-clad people on a planet vs restructuring their bodies down to basic metabolism so no suit is needed.
