Your issues with mining don't make it less secure. The energy it uses can aid in stabilizing energy grids and countless other uses. Asic manufacturing choke points aren't really an issue, id be more concerned about the couple big names in the space. And mining pools aren't really an issue, if they were to attempt to attack the network it would be obvious and people would just stop directing their hashpower there lol. Stratumv2 also nullifies that argument

How does stabilizing the grid make bitcoin mining more secure? If anything that makes it less secure because they are concentrated in single locations and can be flipped off and on by the state.
Of course ASIC manufacturer choke points are a potential issue you said it yourself...there are only a couple big names lol. How do you know newer better ASICs arent being secretly sold to governments? Would be more devastating to Bitcoin because of how limited ASICs are vs CPUs
Monero already has it's own version of "Stratumv2" called P2Pool for years. Catch up slowbros 🏄♂️
