It is true that a cabal of rich people cannot arbitrarily modify the money supply. We instead get a permanently chosen system of money supply that was created by an ideologically driven software engineer who appears to have vanished into the ether. Is it not possible that Satoshi chose a less optimal system than the central banks would? The finite and logarithmic rewards make a huge huge huge difference in the eventual distribution of BTC worldwide, should it become a dominant system. In my opinion, a system where early adopters get unimaginably rich forever is simply unethical.

And if another system eventually wins... then isn't that simply an example of a cabal of people (though not necessarily rich at first in this case) modifying the rules for money supply? Doge produces a different outcome than BTC. That's important.
