Back in the third century BCE, a Greek geometer named Euclid wrote a series of textbooks called the Elements. They're actually pretty fun if you're into puzzle games. Worth an hour at a coffeeshop if nothing else.
In the first book, Euclid lays out five postulates for the geometric proofs that will come: Euclid's Five Postulates.
The fifth postulate, which gives some rules for what makes lines parallel, was the source of much consternation for **TWO MILLENIA**. For two thousand years, many geometers tried to show that the fifth postulate followed from the other four, and thus was unnecessary.
Then around the early 19th century, a couple of mathematicians were like, "what if we just, like, not use the fifth postulate?" This simple idea spurred a century of mathematical exploration that culminated in General Relativity, and curved Space-Time.
I've taken to describing Planet Nine's treatment of money as sort of this kind of approach with respect to crypto. That is, crypto is Euclid: it has some rigid, and perhaps unnecessary definitions as to what currencies and money are, and once those restrictions are removed a whole new universe is out there to explore.
And with that in mind, I invite you to read Planet Nine's Experiments With Money.
