Do you not think supply and demand applies to building chip fabs, or something? And economies of scale?
I'm serious when I say that if there was less asic demand in 2015 and 2018, no matter what the asics were for, that might have reduced the asic capacity in 2021 enough to make the problems we had even worse.
It's possible that without Bitcoin production in the many years leading up to 2020 the supply crunch would have been worse.
Also remember that a huge chunk was based on GPUs and those don't mine Bitcoin, they mine other things.
