I've been opposed to the idea of a national ID card for a long time. This article from merry England is showing what the nanny state's citizens get with that ID card. the government keeps tabs on your big purchases, you know - to prevent fraud - then matches your purchases to your income level to see if your cheating the tax man.
Priceless. Just Priceless.
There is no reason for any federal documentation by my purchases - including firearms. The only possible exceptions would be explosives, undetectable poisons, Enriched Uranium / Plutonium, and nasty diseases - Ebola, HIV, Hepatitis, etc. for research. That's it. It's not supposed to be the fed's job for any of this, but there needs to be a centralized structure in case someone buys stuff in separate states to make a nuke.
Throughout history, governments love to spy on it's own population. Usually under the guise to "prevent crime." today is no different as the feds use web crawlers to read web sites, read our e-mails with Carnivore, and who knows what else. All of this I personally feel is over the line.
We have enough intrusions into our privacy without .gov tracking our every purchase of $X. As our net-presences grow, expect the feds to come barging in with a heavy hand until a court tosses out a few high-profile cases and .gov is reined back in. By then the precedents have been set, and another part of your life is monitored.
The National ID card comes up every now then in our congress. Eventually I fear it will pass and then we will be in for a whole new level of Big Brother. There is a clip on YouTube about the National ID card and how the health care companies will use it to up your pizza costs by having high cholesterol and a "fat tax" on the sausage pizza. I'm at a clients so I can't go looking for it.
