I agree that the BTC miners are behaving legally, and in some sense they have a moral responsibility to maximize profit within the law, but their existence highlights why the law itself is unethical. I think lawmakers have an ethical duty to fix the "burning carbon is too cheap" problem, but the odds of that happening in Texas are low. If we had something like a carbon fee and dividend, miners could become a net good for society just by following price signals.
