Yes good point, I agree that it’s bad advice to ask people to dispose of beliefs which actually work.
I’d also say that disposing of the belief that “an environment of multiple competing cryptocurrencies is undesirable, that it is wrong to launch ‘yet another coin’, and that it is both righteous and inevitable that the Bitcoin currency comes to take a monopoly position in the cryptocurrency scene”, does not forbid somebody from investing in bitcoin based on some other belief.
I think the advice of asking somebody to find better grounding for beliefs is dangerous because it makes it harder for people to change their minds.
Overall the advice is a rule of thumb and should not be followed religiously. If you can coincidentally find new grounding for a belief who’s old grounding no longer makes sense, you should keep it like you said.
Gotcha yea I hadn’t considered those terms; my thinking was that there isn’t an established standard name for this phenomenon. I haven’t seen a standard term for it on lesswrong, but you would think if such a term existed it would be found here pretty easily. Of the ones you list I think “orthodox” fits the best, but they are all highly overloaded and generally used with religious connotations.
I agree that “maxi” doesn’t ring a bell outside of the crypto space right now, but my thinking was to introduce it as a term to represent this idea of “belief in belief” and have it spread from there.
“Maximalist” does have a general definition not specific to crypto: a person who holds extreme views and is not prepared to compromise (Oxford languages).
