The only validation Bitcoin requires is the math that puts your transactions into the public record. Bitcoin does not need validation of big Wall Street names or academics from your favourite school. The same is true for Carnivory and Homeopathy; if it works, it works. PERIOD.
Bitcoin and your diet (where you put your money and what food you put in your body) do not require someone to tell you what you're doing is right. Your finances and stomach will tell you that. You don't need anyone's approval in these things, in every sense. Reality is REAL.
Despite decades of attacks, "alternative" medicine thrives and helps people. Similarly, Bitcoin, after nine years of withering scorn, ridicule and DERP is stronger than ever. The Chinese don't care that you don't believe in acupuncture; they get appendixes removed under it.
If you dont't think acupuncture, Carnivory or Bitcoin or anything that is real works, it is YOU that has the problem. The question is why are you trying to tell other people not to do something that benefits them? What do you have to lose if someone is a total carnivore?
The answer is easy. Collectivists demand total uniformity and conformity to their ideas across the board. That means accepting fiat, vaccinations schedules, salt shunning and every other "normal" thing you can think of. If you reject their thinking, you are a threat to them.
And it doesn't matter which of the many forbidden things you reject; your act of rejecting their world-view is as good as a total rejection for them. They know that, "Falsus in uno, falsus in omnibus" will be applied to them, and their whole system of control will collapse.
This is why Popluar Science runs an attack piece on Carnivory. This is why Krugman attacks Bitcoin. These things are a gateway drug to total rejection of their false reality, norms and ultimately any belief in the State.
