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...
