Even with unlimited fiat, maintaining unrelenting pressure on gold and the mining shares is unsustainable in the long run, especially while simultaneously propping up the broader equity markets. Letting go of support in stocks would bring the house down on the miners. Whether that's the intended effect, and whether it will work, remains to be seen. Add in the algorithmic antics with marginal human investor participation and you once again have the makings of a grand illusion.
Regardless, when you hit
granite, even a nuclear blast may not be capable of doing a huge amount of damage.
I think it makes sense for Summers to view Bitcoin objectively, particularly since it can be analysed in an almost completely academic manner. He's no fool, nor are many of the others in power. Perspective can skew decisions, clouding and shielding the ivory tower from the effects of non-linear system dynamics that can't be easily observed. Therefore what they don't know, or refuse to acknowledge,
will hurt them.
These kind of peoples' existence is basically to ensure control and order. If the methods being used to maintain the status quo are being threatened, it's time to modify the methods. They've been doing a spectacular job of that. Few today think gold will continue its ascent; even fewer are even aware of Bitcoin, much less how it works and what its potential is. Preparing in the shadows where nobody is aware makes the job of maintaining control easier.
Here's a tin-foil nutcase scenario for you: Satoshi was CIA/NSA (take your pick of shadowy organisations) and introduced the Bitcoin system with banks and government having full knowledge of its potential and statistical variance for how it would propagate. Since they have foreknowledge, it would be a sure thing to hold the majority of Bitcoins in existence while slowly restraining its growth via constant pressure; the same strategy as is seen in gold/silver/etc.
For the above situation, the resultant factors would be a refreshed economic structure allowing the world to reinvigorate its productive capacity and an acceleration in speed of transactions. In addition, it would allow the status quo to persist during a paradigm transition. Most of the work subsequent to introduction will be done voluntarily, and any internal divisions would likely leave the leadership in a position of apparent weakness, at which point new ones may emerge. The new leadership could be composed of savvy individuals demonstrating proficiency and maybe bringing a powerful innovation that placates and ingratiates them to the community, or sleeper(s) already part of the community.
Overall, it may not even matter - the Bitcoin paradigm and decentralisation of most elements in human society could prove too great of a transition to be properly harnessed.
