What's so bad about a national ID card, or some sort of standards for IDs?
Right now, the TSA and other federal agencies have to be familiar with the IDs of 50 states. Then each state has several designs. Driver, non driver, learners permit, over 21, over 21, past designs still in circulation, etc. There are literally hundreds of possible different IDs out there, all with their own designs and security features, it is impossible for everyone to know them all. And then everyone who looks young enough to get carded for alcohol and travels to other states frequently has had a bartender give their out of state license a funny look and stare at it, unsure if it's fake or not. So what's wrong with standardizing ID cards? Other countries have done it. And if your concern is privacy, or having your information in a federal database, guess what, the government already has that. Unless you don't have an SSN, don't file taxes, and live in a trailer in the middle of the woods completely off the grid.
