I think any time someone says the market is or isn't efficient, I want to ask them how they define efficient. There are tons of underlying assumptions that I think need to be examined

I am defining based on the market's ability to accurately price based on current information and expected future events.

I think it's the concept of accuracy that I'd question here. How would you know if a price at any given moment is "accurate"?
I agree that markets are becoming more self referential, but if you factor that self referentiality into what you consider as relevant information then I'm not sure what it means to say that the market is not efficient

You can't know for sure but a stock trading at 100 years worth of revenue probably isn't priced efficiently. Even if you believe that stock's revenue with 10x, you can't possibly know that for sure.

What about bitcoin that has no revenue?

Typical commodity markets are likely priced fairly efficiently based on expected supply and demand. Bitcoin I am not so sure. We have known production but we can't anticipate demand very well and at what prices supply will unlock as people sell to take profits. I think the Bitcoin market will be highly efficient when it is 10x the size.

I think my overall point is that the notion that price should reflect net present value of earnings is itself a bit of a philosophical/theoretical construct
It's related to the last period problem that makes some people like Eugene Fama say that bitcoin can't have value
If these are just theoretical concepts. In practice most people are just looking at what price they can flip the stock at after X years... the theoretical infinitely lived agent that looks like the present discounted value of earnings just doesn't exist in reality
That's exactly what I asked in the referenced post.
