good direction but impractical.. a tech lead at Starbucks quipped "we don't actually know how many people work at Starbucks right now" .. huh? because, though they do have modern cloudy tech, there is meat-space time involved in edge transition from state of employed to not-employed, etc. So it is true, even with "perfect" observation of events, the leaders have ranges, not hard numbers.

So it is with markets. There are indistinct conditions that may exist for some time, and decay, and financial privacy, etc. So even given "perfect" observation of events, it is not fully transparent.

Nor would you want it, I argue. Once you as an individual are involved with markets and partners and committed relationships, some faceless bureacracy is tracking your parking spending? or more to the point, your ownership stakes? So we must re-invent public markets. Too much to change at once, and imperfect cooperation, so.. set a direction. "messy"
