I feel that automation will completely wreck your vacuum analogy. If AI and automation are the ones producing something that is desired, how much will it cost? What happens when the cycle is complete with solar or fusion power and the labor value approaches zero.

I think the current economic model will have to be radically altered. Especially when space travel is factored in and resources become post scarcity. Furthermore, digital assets are already approaching post scarcity with nearly limitless information, education and entertainment being open source. Even the block chain technology that allowed this platform to arise is open source! I feel Austrian economics was good for a less technologically developed time.
