Genesis block = big bang.

A single instance of time, block for bitcoin & second for universe, in which order emerged from nothing (chaos).

The universe was in its higher order state during the Big Bang, as was bitcoin. This is not an artificial cap, it’s an observation of reality.

All 50 btc in the coinbase = all 50 bitcoin in existence in Genesis Block. Never again has that happened or will it happen. This is pure information. Satoshi created entropy in this domain (heat via cpu) and resolved chaos (created order) in cyberspace.

Entropy created = Entropy resolved.

This means that all energy expended by the miner in the form of entropy entered a new domain where the “temperature was absolute” there were only 50 units at that time vs 50 in existence. Everything is accounted for.

The issuance of new coinbase from every block after created entropy within Bitcoin that required resolution due to the dilution in the supply of bitcoin.

Those new 50 btc in block 1 were representative of now 1/2 of the total supply. Meaning the temperature reading in block 1 was 50 bitcoin. But we know the exact supply of bitcoin. The energy was most dense in genesis and only Genesis. The universe is no different.
