I've kind of always gotten the concepts involved in it, just never put a lot of thought into it.
I can see it going to the way of 'everything is now crazy expensive and poors are locked out', but otoh I could see it also going 'since we think everything digital has value, none of it does' IE the plot to 'The Incredibles'. In all likelihood there will be both of those extremes operating in tandem rather than all of one or another. The trick as always is ID'ing the things that will take off early.
Either way, I foresee enormous upheaval over this in the not so far term. Finance is part of it, but data itself is going to be swept up into this whirlwind if it picks up enough steam. There's also trying to foresee what the major gov players will do when a critical mass is reached that threatens their power over information. Not over $ per se, but data. That's assuming no such agency or CCP Mil intel doesn't already have their tentacles into ETH at the ground floor, which wouldn't shock me in the slightest.
This is approaching derail/tinfoil territory though, so grain of salt and all that.
