Google provides me with a service, one that I willingly use, in exchange for bits of information from me. I entered into this agreement willingly. If I decide I do not like Google, it's services, or it's EULA, I can ditch it and go somewhere else. I could even come up with my own search algorithm and email service so I would never have to use Google again.
Chipping me at birth strips me of my ability to choose whether I want it. Not to mention that saying, "We chip you, you get to live in our society, the one you were born into, not the one you choose, in exchange for all of the crappy services we can offer you." And even if the services are decent, or you choose the society, it's still coercion if the chipping is a part of the service most people do not want.
