I'd love to be able to use that argument, if I may.
There's a "debate" (if that's the correct word) raging in Australia over
this very thing. Our beloved conservative government wants all ISPs to
store metadata for two years (anti-terrorism, you see), saying "It's only
metadata", whilst the progressives are saying "With the metadata, you
don't need the data".
Our equally-beloved Attorney-General didn't even know what an IP address
was, calling it an "electronic address", and kept contradicting himself
over whether URLs would be recorded or not; the job of selling it to the
sheep was given to our much-liked Communications Minister (who once ran
Ozemail, as it happens), and is clearly uncomfortable with it, but he has
to follow the party line.
So, I'd love to be able to use that argument here in Oz...
