> If we imagine the ideal future 100 years from now, with a more balanced world order and economic justice for all, then we have to experiment with radically different systems at some point in between.

Sure, but I think for any effect a bitcoin-like system has any chance to have on the US's ability to wage war, it will have the same effect on the US government's ability to fund massive social programs. That is, bitcoin is going in the opposite direction from what is needed for achieving the world we hope for.

> My takeaway from the issue of its energy usage is that trying to save the climate by discouraging energy usage is kind of fruitless because society will always want more; focusing on replacing polluting energy sources with clean ones is the sustainable systemic solution.

While I agree with you that this is how things are looking, and it is also the most important long-term goal, I personally don't believe that we have any hope of avoiding catastrophic climate failure if we don't focus on drastically reducing consumption in the short term. To me bitcoin has proved exactly how chasing free economic growth will always drink up any electricity we can produce.
