This is a great theory. I am waiting for it to come true. But for now there is one problem with it — currently the cryptonetworks are not supported by their utility — but by speculation. And that speculation for now seems to be very far from an efficient market: https://www.bloomberg.com/view/articles/2017-12-21/blockchains-go-well-with-cocktails. That is distorting the incentives in a big way — and it will take a long long time to weed that out.
