Not a popular opinion: but I do believe there is a non-zero chance that the NSA created Bitcoin for this exact Fourth Turning purpose.
I've thought about that a bit. The only issue I have with that is that it doesn't allow for the amount of control that they typically aim for. It's too stabilizing, too air tight, with the only think I can think of being a vulnerability is is they know that over time they will be able to acquire most of not all BTC for themselves.
