Found the estimate in the report the Pentagon gave to Congress on this issue in 2013. Your proposed action would take the US, alone, 15 years (https://imgur.com/olWM3Xi).

China has been maintaining a majority share of production for at least a decade at this point. I would wager that while that your proposed response is short as a phrase, actually getting production to match the currently relied-upon volume without China would take years, and I don't think stockpiles would last that long.

China is keeping things surprisingly civil considering they could just limit the supply of or manipulate the cost of rare earth minerals. Many Western companies would soon find themselves in Huawei's shoes, counting down the days until the stockpiles run out.

Do you have any evidence that this genetic information is being used for law enforcement purposes? What I read in that chapter you linked only covers that the tests are being done (for a legitimate reason).

Not that I'd need much convincing; this is old hat for the US police state, which has police departments regularly scare parents into giving police their children's fingerprints.
