So you don't ever take advantage of an ICE? Fly a plane? Drive a car? Nor do you ever get a delivery to your house.

In other words, those things work because you directly or even indirectly support the system which causes those sorts of catastrophes to happen.

Isn't this just the "yet you participate in society" meme? We all can and should attempt to reduce our impact, that might mean we don't own a car, or we fly less frequently and take trains instead, perhaps even just working from home... If I need to fly from North America to Europe, I really don't have a choice. You could do it by boat, but ships are largely powered by fossil fuels too. That doesn't mean I actively support fossil fuel companies.
