I sell all my previous devices on second hand markets like eBay. That question becomes "not my problem:" whoever else is buying it has some kind of use case even though I am done with the system and it no longer fits my use case anymore.
I think that, for the parent commenter to my original comment, this Intel Mac no longer fits their use case. They can fight it and suffer or get the right tool for the job. I'm sure the person who buys it from them won't care that the current version of Homebrew doesn't work on it.
Intel Macs run Linux very well, I might add.
It should also be noted that, yes, most electronics eventually get scrapped for parts and raw materials. It doesn't really take all that long for important components to fail to a point where a computer is not really worth dealing with anymore. Yes, they can be repaired in many cases, but that's only generally worth it to a small group of vintage enthusiasts (and I say this as someone who very much enjoys vintage computing myself).
