"Economy" doesn't necessarily mean "monetization" -- there are lots of parallel and competing economies that exist, and that we actively engage in (reputation, energy, time, goodwill, etc.)
Money turns out to be the most fungible of these, since it can be (more or less) traded for the others.
Right now, there are a bunch of economies being bootstrapped, and the bots will eventually figure out that they need some kind of fungibility. And it's quite possible that they'll find cryptocurrencies as the path of least resistance.
I’m not sure you’re disproving my point. Why is a currency needed at all? Why is fungibility necessary
