Even with decentralised exchanges, the moment you want to spend in fiat money, regulators require information exchange with the tax authorities. Even decentralised exchange require - as far as I know - ID verification to do some fiat transfers. And I didn't even touch the subjects of fixed IP addresses (which are usually geo location fixed), behavioural analyses and in next steps when we have sufficient data collected combined with computing power quantum computers will provide us, will most likely be able to identify an individual based on behavioural (online) patterns, the fact that individuals have physcial presence anyway in society, and also the topic of less anonymity when we use addresses like with Steem and Steemit. Next to that our tendency to throw whatever we like on the internet anyway, including all sort of details like meail addresses, phone numbers, addresses and so on. The later of course not by those who really want to stay anonymous, but the majority of the newer generation are becoming so transparent through social media and other online services (Linkedin included), that it is not difficult to find someone, hence the need for anonymity may not be a need for the mass at all.

Wrt the few years towards a total crypto based society, I think this is not a few years, unless with few we mean something like a couple of decades. As TCP, as the Internet, as the mobile phone required decades to get in the hands of the mass, also crypto will take at least that amount of time. That are realities we have to realise. How much we want to change things, and how much technology allows as to change already today, it generally requires new generations to actually adopt the new possibilities.

What is your business if I may ask?
