There are many bitcoiners who agree with you on GW so you should at least know you aren't alone.
The best way I've found to think about bitcoin's energy usage is on a relative basis to other things that use energy. That wikipedia RFC states McDonald's toy production consumes more energy than bitcoin and clearly bitcoin is a less frivolous use of energy. Another energy stat is clothing dryers in the US alone consumer more energy than bitcoin.
imho the camp you have to choose isn't between bitcoin and the environment. It's between whether consuming energy for human flourishing is worth it or not.
