Earlier quoted context omitted.
Some rights, but not all rights. You cannot (in any country I am aware of) contract away your right to life, nor turn yourself into a slave in exchange for your debts being forgiven. The latter used to be possible, if I understand serfdom correctly. Question is, should data rights be alienable or inalienable?
Thank you for articulating, explaining stuff better than I can.
If you're talking about what rights you should have, that's fine. Currently, however, there is no defined right in the US such that service providers like google, Facebook, etc can't make use of the data they acquire from you. If you consider data on you to be more valuable than the service provided, don't use the service.
