Absolutely not. Massive corporations (including many that are state-owned) being allowed to dump MASSIVE amounts of CO2 (etc) into the air that we humans need to breathe completely for free is not anything like the reductionist view of humans breathing air as an externality. For one thing, humans are fed ultimately by photosynthesis, which exactly compensates for the oxygen we breathe and CO2 we exhale.

But fossil fuels, on the other hand, are massive stores of an atmospheric state tens or hundreds of millions of years before humans existed. CO2 levels were so high, the modern human physiology isn't well suited, and your mental state would be as if you were in a stuffy room. The sun even was slightly dimmer at the time, it was so far ago.

And secondly, the amount of oxygen humans need and CO2 we expel is about two orders of magnitude less than that of burning of fossil fuels. To make that comparison is extreme dishonesty.

Requiring companies to pay for the externalities they foist on others is not "wholesale curtailment of liberties." In fact, companies levying those externalities on us without paying for it is stealing, i.e. the wholesale curtailment of the liberty of everyone on the planet. You have it exactly backwards.
