dear @crypto.piotr nice to see you here active again haven´t seen you for a long time here ;)
And yes in the majority of your arguments I´m with you, just the last point

I sometimes wonder what this space would look like if the majority of mining facilities were already owned by various governments.

you must not look so far to see some of these guys doing exactely what you mentioned, there is Nicaragua but they mostly buy them (maybe not all), the US-Boys actually just confiscate them (actually maybe later they will change habits), Buthan has done it with great power and still will do it including powering up their mining facilities, don´t know what China and North Korea does, so you see that´s not a future term its almost happening in several corners of the earth.
And to break it down for the seeking of newer and cheaper energy resources, that´s not a hard thing to reach, if people will use their brain, we not only have Wind, water and solar power, we also have billions of tonns of waste in anny state worldwide, so the use of this energy via Waste2Energy plants can produce energy out of nothing for costs below the cost of wind and solar and water and moreover for less than a nuclear reactor and wouldn´t harm the environment. Some of the big mining players have already checked that out and take that in consideration to solve a huge environmental problem and gain money at the same time with mining BTC out of this very helpful task, that´s win win pure, we all just need to use our brain for what it was designed for ;)

So to make it short, BTC ist solving a lot of problems, environmentally, financially and socially, by the way I never heard about Visa or Bank of america thinking of using a W2E-plant to generate their tremendos amount of energy what they burn daily without having any bad thoughts about it ! Did you ?
