It seems to me like you could use the "oppressive government" argument against most technological innovations, period:

- centralized postal system - "now the government can read your correspondence to other people"

- telephones invented - "now the government can listen to you talking to other people"

- invention of the Web - "now the government can track what you read, watch, etc"

- e-commerce takes off - "now the government can keep records on what you buy"

- GPS becomes popular in cars - "now the government can track where you drive"

- GPS becomes ubiquitous in cell phones - "now the government can track where you walk"

Perhaps we should consider more than just the worse possible way to use a technology when the idea of it is broached.
