It is commonly recognized that Democracy could not exist at a granularity where everyone verifiably gets to contribute to every decision (even if only to abstain), including throughout the resolution of unsettled downstream decisions during implementation of settled upstream decisions.
This is very much not a surprise to anyone.
For any Democratic system to work, it must include systems of delegation.
One can usefully talk about tradeoffs of different kinds, granularity, processes and limits of delegation.
