If it's good enough for significant space and time... it should be good enough for people (in my opinion at least).

Obviously humans don't have space ships, and this is just a thought experiment. But like I commented elsewhere... 'the credits' you saw on 4x games - Galactic Civilizations, Stellaris, and Master of Orion... look eerily like Sats.

In some games they even had the lightning bolts as 'universal energy credits'. Isn't that essentially what Bitcoin is?
