This is kind of hilarious phrasing because these metals are actually more abundant everywhere except for Earth because on earth where they sunk down to the core of the planet. inside of asteroids and things like that there's not enough gravity for that to happen.
Rare earth metals are actually pretty common everywhere else, China just cornered the market by having no environmental regulations, paying people to come into the United States and bitch whenever we make a rare earth facility because of environmental impacts, and using subsidy to undercut the rest of the world.
The moment trying to tries to block the world off where metal creation in the world will take off again.
