Saife was imagining a world where dollars no longer exist, and Saylor wasn't.  It seemed to me 45 minutes of it was just not realizing this point.
IMO, there is no yield in a hyperbitcoinized world because there's nowhere for it to come from.
There is yield in a bitcoinized (SoV) world because govt currency will still be there to rise like an exponential tide to fool people who cannot see it.  
Which of those things happen dictates who is right, but Saylor in particular was not at his best.
My two cents anyway. 

 Talking past one another for sure
