Edit, just to give people an idea of where he's coming from ideologically, these are some of his comments that show the kind of world he wants to see:

"law-abiding taxpayers like me are subsidizing criminals to use cash and not pay taxes"

"so getting rid of cash has some other benefits which will lead to unexpected changes. For example for economists, getting rid of cash means that you lose the zero lower bound on interest rates. You can't have interest below zero because if you drop interest rates below zero people will just draw out the cash and just hold it. If you don't have cash you can have negative real interest rates. So getting rid of cash has a lot of benefits."

"So if you allow us technologists to build the stuff so we build something like Bitcoin which let's pretend it's anonymous. Do you know what you get if you let us build that? You get a giant electronic Somalia. If you want to live in a society which is entirely driven by anonymous cash, where the rich aren't accountable anymore, where whoever's got the most money can be the warlord and do what they like, well that's what you're letting us build now"

His demonization of cash remind me of this:

"The cashless society – which more accurately should be called the bank-payments society – is often presented as an inevitability, an outcome of ‘natural progress’. This claim is either naïve or disingenuous. Any future cashless bank-payments society will be the outcome of a deliberate war on cash waged by an alliance of three elite groups with deep interests in seeing it emerge"
