Why would the govt want to know what boring fuckers like us do? Really, anybody who's read or seen any future-world sci-fi stuff should know that all this is inevitable.
Also, the Orwell stuff isn't totally on the dot. In 1984 the (I forget the govt's name) institute wanted to de-humanise every person, like, destroy even their sex drives.
I'm all for ID cards, 'cause like Jord said, if you have nothing to hide, then you've got nothing to fear.
