Well, you're assuming that the manufacturers would get involved with specific disassemblies, the realistic process would be that the current process of mass recycling random home appliances (which is mandatory at least where I live) when these appliances are ripped open to recycle e.g. metals would also include desoldering the electronic parts, sorting and testing them and putting them back into circulation. We don't do that, probably because it's far too expensive because disassembly is less automated than assembly, but a genuine shortage of core components (the set of which would not/should not change over 10-20 years) could be helped this way. A big assumption that I'm making is that you would be extract the exact same components from many different devices, so you can build a washing machine with a component supply that's part new components and part 'reused' from all kinds of older washing machines, fridges or cars or smart toasters or whatever. This IMHO is true for generic electronic components (which are quite cheap but still add up in volume) but might not hold for chips - however, my initial argument probably was that if "chips-for-not-so-powerful-appliances" currently are structured to not be interchangeable, then perhaps they should be.
