Except intellectual “property” isn’t property. It is a (supposed temporary) license granted by our constitution to creators as an encouragement to create. Your “ownership” monopoly is subject to judicial interpretation of its constitutional roots. Therefore, for copyrighted work, we have concepts like fair-use, which have no analog to your ownership of a house in Maine.
Your writing has value to the public domain as well as to you. It is reasonable that the courts try to strike an appropriate balance between these two often-conflicting goals. It is not up to me to decide if what Google is doing is right, but it is wrong to play the “property” game when discussing it.
