On Cash
Another point is that cash allows you to buy unethical things and illegal things. It allows economical activity on the edges of society. Some of those edges are bad, but some are good.<p>How could you run a gay bar, in a place where gay bars are illegal, and the government could just block your payments? How could you sell marijuana and build the legalize movement, if government could just block those payments? How could you run a whistleblower leak site on the internet through donations, if the government can just block all payments to you?<p>Deciding what people can buy and cannot buy sounds <i>great</i> if you're the one in power. But if you're not, it will pretty quickly turn into another form of tyranny.
