So, you're saying that there should be some kind of powerful institution that is capable of defending the currency against manipulation attempts if necessary and thus ensures a reasonable level of stability in said currency? This concept seems somewhat familiar, you might even consider it a crypto currency's Central Bank.
What I find funny w.r.t. to BTC et al. is that people are slowly starting to find out that living in the currency equivalent of the Wild West is not as much fun as it sounds at first. First, there were calls for more government regulation and a higher level of accountability on the side of infrastructure operators and now even the idea of some entity defending the currency against attacks seems like an attractive prospect.
My prediction is that at the end there will be an epiphany that our real world currency system is constructed the way it is for a reason. It may not be perfect, it certainly has some major flaws but at the end of the day it's still better than the alternatives.
