The shrinking of privacy when buying stuff isn't new. Everything is already there with credit card payment. Most governments/judiciary system can already ask for this data (and it is tied to a real life identity). Edit: and since like many people I already lost that battle (I use CC for most purchases), I might as well get some benefits out of it. My CC company doesn't offer me any fancy spending tracking, and I don't trust companies like mint.com as much as I trust google to deal with my data (and I'm not sure if Mint works outside of the US).
