TL;DR: It isn't cheaper to get it these ways than by buying them.

I havnt read it but if there is a shortage of specifically memory modules arent the modules still going to cost a ton?

linux users are one production step closer to just mining lithium themselves.

Um, aren't memory modules the commodity product that is in short supply?

Recycling the broken ram sticks isn't done as far as I know so it kinda makes sense. New memory and used working sticks is hard to get. Broken sticks most likely not so hard.

I thought part of the reason for increased ram prices was a shortage of chips and not the assembly of ram modules

Not a terrible idea if you have a good process. Not sure my hand is steady enough to do it without a bga machine, but solder paste, custom masks, and a diy rig for lowering the chip could possibly do it.
