It IS plain enough. "shall not be infringed" is very clear. Relying on the introductory phrase to be part of the ammendment and to be a restricting part is not a valid English usage. A similar construction might be:
"The dependence of all living things on photosynthesss being recognized, the right of the people to enjoy the fruits and benefits of photosysthesis shall not be infringed."
In this case it would not matter that all living things don't need photosysthesis, (there are microbes that exist without light). The right to enjoy the benefits of photosynthesis is nevertheless still invoked.
