Ok, from the talk, she lost me at the idea that you can have value without scarcity.  Built-in scarcity, proof of work, and halving the block reward over time prevents the inflationary pressures we see in state fiat currency.  Abundance results from free market efficiency that rewards the best product at the cheapest price showing that deflation from efficiency is a sign of a healthy economy.  See televisions.  But this presupposes a hard money.  The decentralized price system from a web of interconnected individual choices using hard money produces abundance and efficiency instead of the Communist ideal of a command and centralized economy, which had produced shortages, corruption and rampant inflation in every case and in every culture it has been tried.  Analysis and engagement.
