Excessive. You can call an airline, hotel or taxi company directly, text your friends or pay for dinner with cash. Your inner paranoid is drawn to the convenience of the services that google offers. If you don't want one company to have a lot of information about you, then don't use that company for everything. Google loves data. But generally in the aggregate, not the personal. I've yet to see anything even remotely creepy of any kind from google advertising. "Hey karmacondon, we saw that you recently booked a trip to las vegas, took a self-driving cab to the Bunny Ranch and used your Google Wallet to pay for two hours with someone named 'Bubbles'. Can we interest you in some anti-itch creme?". That kind of personal intrusion just doesn't match anything I've seen from Google, and until that day comes I'm willing to give them the benefit of the doubt. MasterCard and Visa know more about you than Google ever will. You can't book a flight or check into a hotel without using a credit card, which is directly attached to your name and is trivially subpoenable. If you're really worried, there are ways to live a cash only existence, but it isn't easy. Some level of trust is required to live in modern society. It's good to be skeptical, but it always comes down to the level of inconvenience you're willing to trade for privacy.
