You're very right to say that there is a lot of resistance. Also, I agree on the cognitive load aspect. It may be the root cause of much of the resistance. It's simply toooo tiresome for many people to adopt new mental models to help them grasp what's going on. Hence, they resort to their old models, which in the case of crypto would be to dismiss it as a scam.
The truth, however, is that it's an entirely novel way for people to communicate value that is constantly creating network effect. In hindsight, maybe 10-15 years from now, cryptocurrency adoption will seem inevitable.
The same people who are aggressively dismissing it now will quietly embrace it. We are the early ones and massively privileged because we overcame our initial skepticism for various reasons be it our natural mental flexibility or having the right people or things influence us at the right time.
I can so relate with this ^^^ !
