The death of the Bitcoin economy is the isolation from the real world.
I think this is the more important point. Merchants like us who are basically extraterritorial but legally liable face an uphill battle dealing with the conglomerated banking and payment processing interests. But Bitcoin only serves a utilitarian purpose for us as long as our customers are able to buy it with their paycheck and redeem it for bread, or something they can buy their bread with. We're wholly dependent on the functioning of the trading houses, they're the ones who absorb our risk and act as our interface with the world.
Now if it's not Bitcoin, it's gonna be something. Bitcoin didn't spring out of a void, it came out of a basic need that's developed to hold your value outside the government-controlled monetary systems. That demand is only going to increase as further corrupt regulation, sponsored by the banking sector and rammed through by their government cronies, continue to tighten the noose around the middle- and upper-middle class people who spent their lives playing by the rules only to see their life's savings swept up in the giant ponzi scheme that's playing itself out around the world. The further we sink into the crisis, the more people see they have no control over their own survival, the more realize they've been turned into slaves to these interests, the more people will turn to alternate currencies or anything that puts a little of their wealth off the grid for the future. The most productive land in Soviet Russia was the 10% that was set aside from collectivization for personal gardens in the '60s and '70s. [correction: it was 2% of the land, and it accounted for 1/4th the agricultural output.

Then and now there was a system of corruption masked by, and in the name of, social equality...where distribution from the able to the needy still turns out to be another way for parasites to rape the innovators and producers of value at the point of a gun. Yet the fact that the demand existed then, and exists now, for ways of storing personal wealth outside the crippling system of corruption, did not and will not make it a mainstream action. Even now, in North Korea, there are people privately producing what vegetables they can get away with growing and selling...they're basically in the same position as people who want something like Bitcoin to store their wealth in the Western world. A much worse day-to-day position, but not essentially different: Their product isn't their own.
"Fiat" isn't so much a description for currency as a description for the means by which governments disabuse citizens of their God-given rights as human beings. By fiat, they declare their collection of taxes on penalty of imprisonment. By fiat, they make it illegal to buy or sell outside of the channels they regulate, so they can take a piece of everything. By fiat, Steve Wynn can open as many casinos as he wants, although he personally could never do what we've done. By fiat, we're barred from taking bets in the US, or trading normally through other methods.
But we, and others, will make the most of the opportunity to blow this whole worm-ridden, corrupt corpse of a system sky-high. Maybe not us, maybe not Bitcoin, but the tighter they pull the noose on the ordinary man the more resistance they'll meet.
So fuck them. Bitcoin -- whatever else it might be -- is proof you can't keep humanity in a permanent state of oppression anymore. It might be a wild ride the next few years, and I'm sure it will be. We're gonna keep riding the waves.
