0. Bitcoin supporters are so batshit insane that many folks simply don't want to be associated with them.
That's not a valid reason at all. Economics is all about incentives. Given a strong enough incentive, racists will hire minorities, Sexists will hire women, Anti-semites will do business with Jews and Homophobes will provide goods and services to gays. History is littered with sane people lining up to be associated with whackjobs when they had an incentive to do so.

You've got it all in reverse, Women won't hire sexists, Jews won't hire Antisemites and Homosexuals won't hire Homophobes. Bitcoiners are the ones who want to bring on economic Armageddon, want to evade taxes, subvert the government and who hold a fundamentalist attitude.
It's the Bitcoiners that subscribe to the us versus them mentality not normal people.
Do I? Women complain all the time that their bosses are sexist. Many minorities, possibly even most of them believe or suspect that their employers are racists. So why work for them? Because to them, it's better than the alternatives. It's all about the incentives, Man.
I could argue that your characterization of bitcoiners is a straw man, but there's no point because it's irrelevant. The price of gold isn't determined by the goldbug's whack conspiracy theories. It's determined by supply and demand. It doesn't fucking matter. The issue holding bitcoin back is scalability and network capacity. Everything else is incidental. Branding only matters when deciding between two or more nearly identical choices. Coke or Pepsi. Visa or Mastercard.
