BTW, there is another bit to the extended clinic seed story.

Everything uses resources, and whether it’s rare elements, electricity, computing power, or access to the technology itself, uneven distribution of resources is not going to miraculously disappear.

And there's something else to consider, cryptocurrency is rapidly running out of time to be relevant. Once Drexler style nanotechnology is developed then, in just a few minutes, you'll be able to make anything you want yourself. That would even be true for real estate, after all the surface of a planet is not the only place where space exists. And once you reach that point what use would you have for money?
