Another misunderstanding about what Satoshi "envisioned". Don't you know he said he expects mining to concentrate into big mining farms?
That doesn't change that a few owners of mining farms will eventually choose which Bitcoin upgrades to support and reject at will.
As seen with Monero, attempts to restrict miners often just lead to covert development of ASICs/FPGAs and even more centralized mining
The Satoshi Bitcoin white paper only mentions CPUs. Now people have to use expensive hard to use mining purposed machines that are otherwise useless. That is a clear need-2-fix problem
