Hmm, shouldn’t we be looking at this thru the resolution of entropy? The genesis block is the only time historically in which the resolution of a 32 bit nonce space resulted in the initial quantum of structure, only in genesis is the coinbase representative of the 100% of the entire system. Satoshi defined what D=1 means. It’s the quantum of entropy and its relationship to Satoshis. It sets the thermodynamic anchor for which all future transformations are based off of.
