what about "rent capture" and "fiat risk"?
Fiat risk: inflation.
To paraphrase Silvio Gesell, an economist in favor of symbolic currency almost a century ago, "All the physical assets of the world are at the disposal of those who wish to save, so why should they make their savings in the form of money? Money was not made to be saved!"
ie: you don't need to buy whole companies outright to avoid saving in currency.
