I don't think you really understand what cost means in this case. Or a compromise.

Thinking that cost just means paying more -> bad is a very simplistic way to look at things.

Cost, especially via taxation, means setting aside a part of our productivity as a planet towards making sure we don't destroy ourselves. Everybody should contribute because everyone has skin in the game. By taxing CO2 specifically, you force people towards choosing more sustainable choices automatically.

Understand that you can't have a completely free market and an environment in which you want to live.
