It's a bit like the Easter Islanders cutting down all of their trees for wood. Where does Google management think they'll get search results if they kill the entire internet? Has anyone at Google thought that far ahead?

The internet they dream of is like a large mall. It consists of service providers selling you something, and Google directing you to them in exchange for some of the profit. The role of users in this model is that of a Piñata that everyone hits on to drop some money.
