It's like worrying about how many times you personally ordered Chinese food affects the price of Diesel fuel in India. It's an absurd leap of logic, and the parent is right to call out these arguments which are almost always emotional.
And given that right now they are clearly not, what’s your plan until then?
Imagine a world where the only energy you do is use was generated by a stationary bike you had to ride yourself. You would, generally speaking, use that energy differently than energy you would pay for--you would generally reserve your effort for worthwhile things, and would be averse to farming energy yourself just to power frivolity or vice. How you determine what to put your energy into would explicitly be a moral question.
Instead in our world we an abstractions conceals the source of the energy. But if the moral concerns from the first world had any weight, they haven't lost it now; if energy is anything short of completely free we should by the same logic be averse to expending energy on worthless work or vice. The human being is not a utility monster, but something very different, and moral questions of this sort are central to how it navigates the world, they should not be dismissed.
Wouldn't your argument also compel us to use steel as if it were gold? Salt as if it were saffron?
Ok so I do need to worry about energy so that I can identify these unaddressed externalities and work towards updating the rules. You can to care before you can get involved in this stuff. You can't tell me not to worry about it and then also say that it's basically my fault for not getting involved if the price is wrong.
