This is not a problem.

I see the government wants to keep a massive database of all of our purchases.
This doesn’t worry me. Who, precisely, is going to read and correllate this data? The already overworked and generally-terrorism-impaired intelligence community. Keep all the data you want about the books I buy, the weapons I keep supplied with ammo, and the meals I eat. I don’t care.
Information glut is going to kill any real chance of our vaunted intelligence agencies actually finding anything before it’s too late. This is what happened before Pearl Harbor — the ratio of noise to signal was way too high for any meaningful intelligence to be developed. This kind of stupidity just adds to the noise.
