I don't give a fuck if the NSA is spying at me, if they are not doing something wrong with it, that's all. Anyway your government already have your bills and ID Card, your arguments against the government are full of bs. If they want to kill you, it will be fast. If they want to keep tracking you by watching in the e-commerce's databases they will find your new adress too.
They aren't trying to kill you, well in most cases anyway. What they are trying to do is actively manipulate you. For example, you ignoring that the NSA can gather information off of you, or these days any Tom, Dick or Harry can, isn't a problem as long as they don't do anything bad is ludicrous. Do you not consider being manipulated into buying products as bad? Just because you've shown some interest in it in the past, or visited a related site. We on in a world full of advertisements these days, and they will actively try to manipulate you into buying their products, and they use your previous data, and site history to determine how best to make money from you. How is that not bad?
There's also the element that most exchanges as mentioned above have been hacked. That means, your trusting someone to hold your personal documents, and if they are ever compromised you are relying on them to hold them securely. However, history has taught us that even security firms have made massive security mistakes in the past, and continue to do so. So, how can we expect an exchange to follow all the protocols? You can't, because you can't trust them to do that.
