It is a long list and I am not going to read through all of that. However I would say from my experience things are not always "you can't do it" but rather "you will lose some efficiency".
You can build hard drives without rare earth magnet. It will just be slower and it may be fine today as most are used for archiving or video recording, etc now that we have SSD. You also don't NEED helium in many of the hard drive today, it is used mainly to reduce air drag and improve energy efficiency, but ok without it. Semiconductor would be a tough one but a lot of the electronics may be slower or going back to an older generation in performance if they don't use it. We can find a way and the economy typically will.
Will we die because of the lack of rare earth? Maybe in the medical field, maybe we can have those excluded with China if we have Red Cross arbitrate with them, they may not want to look bad and waive those. I don't know. I know military use will definitely have some problem and all military need will absolutely need an alternative source regardless.
We just had a great time with easily obtainable rare earth resource that we waste them all along. I love helium ballons but I can see that my grandkids may never get to enjoy them. They already went away in car dealerships as they should have.
