The merit you seem to think earlier adopters deserve is about as substantive as the merit that bankers are the only ones trust/credit-worthy enough to create money.
Throwing in the current bogeymen of the world, the bankers, does nothing to make your case.
Early adopters do deserve credit. Without the early adopter, there is no late adopter. If you want to buy Bitcoin's now, you want to because they are desirable. Why are they desirable though? The answer is: the early adopters made them so.
I try to be careful about my words in the hopes that the meaning is actually conveyed. I said "earlier adopters" for a very specific reason, and I expounded on this reason:
It isn't just the situation right now, this has to happen every time a market or a geographic area started moving over to bitcoin... Every new large source of demand relative to the bitcoin economy is a new large source of volatility
"Early", "earlier" -- both are referring to the same people... those who came before those who haven't yet adopted. Assuming an ever increasing price -- their gain being proportional to the earliness of their adoption.
That's true to an ever decreasing degree. You also assume that demand will come in waves. Why isn't it more likely to come as a continuous (percentage wise) stream?
How much credit are we willing to give to the first half of the Earth that adopts bitcoin over the second half of the Earth? Because they are going to have the same advantage. The only ones who don't get this benefit is whoever comes last. It's stupid and it will be incredibly disruptive in the short term each time. That makes for a long term serious instability. Cycling, if you will.
Again with the cycling; I don't see the source of that. You also make it sound like each of your imagined cycles is the same size. By the time half the earth adopts bitcoin, then half of the potential gains to earlier adopters will have happened. If it was cyclic then each cycle benefits in exact proportion to its foresight. Therefore that is the amount of credit we are willing to give them.
You make it sound like these early/earlier adopters are stealing their benefit or that there is some external party giving it to them unfairly. Everything is a choice and everything has risk. There were identical screams about early adopters last year as the price went from $10 to $30 -- are those who bought in at $15 "early adopters" who should be denigrated in your theory? Perhaps those who choose to be late adopters prefer lower risk than higher reward?
Finally (in this paragraph) you incorrectly conflate increased demand with "disruption" and "instability". These are words that our current political masters throw around without regard to their meaning. Who is to say that they are desirable? Bitcoin is certainly disruptive, and it is good that it is so. As for "instability"... well, stability is only beneficial if you like where you are when you are stable.
The early adopters risked money when it was, perhaps, foolish to do so. Either they saw potential that others did not, or they were better informed than others, or they were lunatics who acted entirely randomly. Whatever their reasons for buying a collection of zeroes and ones, or buying the electricity to run a bitcoin node, that was a risk that could easily have come to nought. As it's turned out, there is a distinct possibility that their willingness to invest time or money early on has resulted in enough momentum to create a potentially world changing financial instrument.
Yeah whatever the tired argument that a few dollars of electricity and participating in a hobby is a gigantic risk worth millions. I really don't care about this, which is why I am specific with my words. But it is so easy and tempting to quote part of a paragraph and bite in as if there weren't anything else clarifying it.
The worth of an action is the value that action results in. Without those early adopters risking those "few dollars" there would be no millions. I didn't quote your "clarifications" because they weren't very clear or were observably wrong (it's fashionable to hate bankers, but to suggest they don't add anything to the world is simply false -- if it were true, then why has the collapse of banks been so traumatic?).
The question, fundamentally, is: who are you to tell people what they should or shouldn't pay or ask for a bitcoin at any moment? That, in the end, is all we have -- offers and acceptances of offers. You would prefer, perhaps, that you be put in charge of price, is that it? You would presumably pick the correct price right now? You would also favour a law that told the population of the world that bitcoin is inevitable and they should immediately convert their capital at your chosen optimum price in order that nobody benefits from future price changes?
