I find it thoroughly hilarious that when someone pokes at your original assertion that "the whole monetary system is going to collapse" - a completely unsubstantiated claim that is hilarious at face value - you shriek about "well what about hyperinflation?!?!?! explain that, checkmate bro"
I could ask you "what does Bitcoin do that USD doesn't", "how will bitcoin topple an international system bound by trade and agreement to minimize risk", "what about bitcoin's obviously huge deflation problem", "what about the huge amount of flaws in bitcoin's implementation today", or - just spitballing here - "why the fuck would super hyperinflation actually happen", which was your original claim...
But why bother? It's much more easy to watch you try to justify it in weirdo ways with claims about infinite money and what amounts to bigfoot. You know, the same way people like Ron Paul robots have been doing since 1981: http://ron-paul.tumblr.com/post/25365125/i-believe-such-a-st....
The only difference now is instead of libertarians having a goldbug, they have a bitcoin bug. Or maybe Ron Paul was right and hyperinflation has actually been going on since 1981, omg?!?!
And to answer your first question: yes, techno singularity nerds are absolutely disconnected from reality if they think the magics of The Blockchain are the solution to actual economic woes, or hell, even daily financial ones for ordinary people. After all, I forgot how much I want a global network that can only do < 10 TPS, doesn't have fraud prevention, and is surprisingly non-anonymous, as well as ridiculously power inefficient. VisaNet only does close to 50,000 TPS with essentially zero downtime globally per year - why's that a big deal?
