I wish more people considered this. Lots of people keep pushing to get rid of cash, for example, because it will "reduce terrorism" or "reduce money laundering" or whatever. But I like using cash, because I don't want my bank, or an anti-money-laundering authority, or anyone else to know what I buy, when, why, how much, or from whom. It has nothing to do with illegal activity, or buying drugs, or whatever.

My parents and grandparents told me about the days before centralized documentation. A birth certificate was sufficient documentation, and of course those could be changed. One could lie about his birthday and not get caught. These days, no one is a person at all unless the government says he is, and even then, he is only the person the government says he is: I knew someone who was a transgender; she couldn't call herself a woman in many contexts until the government said so. This idea of constantly proving that you are who you claim to be, backed by government verification, strikes me as a bad direction to go.
