I think the interesting part here is the relation to bitcoin and a new theory on how to price things. It’s traditionally been assumed that the price of an asset is related to the underlying value it has or the value it generates (eg cash flow). SBF is pointing out that’s not a complete method of pricing assets in today’s world. You also have to factor in “collective agreements”.
Bitcoin is the clearest example of an asset price that is driven by collective agreement. The collective agreement is enshrined in code and algorithms.
