Yes, I think the informed Bitcoin investor is well aware of the value that decentralized peer-to-peer censorship resistant electronic money brings to the table.
I care. Everyone I know cares. The core developers care. The ecosystem cares. I think you are radically underestimating the value of such things.
I'm pretty sure most of them just see mining as quick easy cash. If people actually valued the decentralization aspect then more would be using it for day to day transactions rather than just speculative investments.
Miners? Not a chance. They know exactly what they are doing for decentralization and censorship resistance. It requires large capital investment over many years, and often includes long energy contracts with providers. If you believe mining Bitcoin is 'quick easy cash' I am afraid you are mistaken (in 2021).
Some Retail investors? Sure -- but I'm sure you could find misinformed investors in all fields.
The point nocoiners miss is that holding Bitcoin IS using it. It is storing value over larger periods, and especially through jurisdictions with poor fiscal policies. Many like me will not sell their Bitcoin at any price -- especially not for dirty fiat.
