I think it's probably a lot of motives, but one of them is that most of our (USA) politicians are too old, and frankly many too dumb, to properly grasp nuanced topics like these. They don't understand crypto, or the internet, or cyber warfare, or larger economic conflict, or any number of critical things they should be well informed on. Their prime focus is on getting reelected and pushing their own agenda, not good stewardship of the nation. I agree that they are pandering on the environment point, there are much more valuable things to spend your time on if you're worried about the environment.
