You can make a case for anything voluntarily involving destroying your privacy. Compare to GDR. You were always watched, period. The same's true now, but its partly voluntarily. Is it desirable? You should decide on that on a case-by-case scenario. Schneier wrote several essays on this matter (here's one [1] and a more recent one [2]) and his latest book, Data and Goliath also covers this subject.
Interestingly the more we centralise on our smartphones, the more difficult voluntarily leaving it home becomes. We already put all kind of NFC cards like our bank and public transport on our phones these days. What's next, unlocking the car via NFC?
