If I understand correctly, then maximum blockchain for every new chain is fixed, and if it reaches it's maximum size, then the oldest blocks, one by one, disappear into nothingness.
If this is right reasoning then why should anyone care about genesis block size, since sooner or later it will go?
Shouldn't then everyone be given even the smallest amount of any promised asset?
Who can predict if, over time, even 0.00000001PTS will have or have not a value of some significance?
And also genesis block will be the same for every new chain respecting Consensus, then it's initialization will only be done once in history, with optional later additions to it.
