I thought that they had just confiscated it like other countries, but they are freaking mining it? That's pretty wild, however i am not that confident that getting governments mining bitcoin is a good idea. These countries policy for mining can change over night with elections, and dumping / market suppression is a real threat.
It seems like you only like to look at the negative side of things. Why can't you look at the positive side like everyone else, the fact that governments mine or hold bitcoin shows they also see its potential and importance? Besides, even if we don't like it, what can we do and what good is complaining?
Like Bitcoin ETFs, many people don't like it because it makes Bitcoin centralized but how to prevent all this? How to prevent governments from interfering with bitcoin as it becomes more and more popular? Do you have any solutions? Instead of complaining constantly but still having no way to stop them, we should adapt.
And i doubt that many countries would go this road, as putting this much weigh on critical infra like electricity and depending on the income of that is risky as hell. Especially with countries like venezuela, that would risk their grid that's already unstable enough. And since electricity isn't cheap, it needs special conditions like mining occasionally with waste energy. That could actually work.
Just because you doubt it doesn't mean it won't happen, as iBaba said above: Rome wasn't built overnight. Look at the positive side and expect it to happen instead of doubting and complaining because that doesn't help.
