There's an easy solution to this problem (and an interesting technical video on YouTube):
"Rare earths" aren't really rare. They got that name because they were initially hard to find but we know that is not true. The US - and most countries have a huge supply of rare earth elements - vital for high tech industry - but the supply is mixed with thorium, a natural, weakly radioactive material.
Most country regulations including the US have draconian restrictions on what can be done with thorium that was sitting in the ground, pulled out of the ground, had materials extracted from it, then put back in the ground. But, even though you did nothing to it, you can't just put it back in the ground!

Afterlife Insurance is a great idea, the Egyptians were into that big time, before all the other religions got into it, and a deceased PHB would make a great manager for the um, pyramid scheme.
