The system is more decentralised than centralised at this point anyway. I don't think it's possible, probably one of those things like in engineering where after a certain point continuing with an optimisation gives less benefit (the law of diminishing returns). Megalomaniacs don't like such inconveniences.
I don't see why the money base layer can't be bitcoin. It's decentralised and battle tested and does like the honey badger.
Great to get your view it's really helpful, I really appreciate. Not alone in thinking about these thoughts.
