The only reason the supply chain is at risk is because we dispose of a lot of electronics simply because there's a new version.
When the product lifecycle changes from 1 year to 10+ years, you'll find that people will just keep their stuff around longer and the demand on the supply chain goes way down.
Plus, there will be a shitload of data centers with capacity that will no longer be necessary (because of reduced devices making requests, segregated internet, less connectivity) in apocalyptic scenarios. Those can probably be re-purposed.
We haven't had to get clever about computer conservation because there's been so much supply.
