The degree is the difference and it's a big one. We all trade privacy for other benefits all the time. If the right to privacy is fundamental, then surely I can claim the right to trade that privacy for something else, too.

(Note: we all do this all the time in both explicit and implicit ways. We give away private data to obtain loans, we invite people into our homes and to view our bodies, we tell important secrets to build relationships. Privacy is valuable, and we use it like it's valuable. That's what's going on here, too.)
