But who determines the cost? Who amongst us does not produce CO2?

YOU are the customer if each of these externalities that you are arguing against. Are you willing to shoulder the cost?

That's the whole point is it not? We should each shoulder the appropriate burden of impact in the price of all the goods and services we buy.

If that means some businesses are no longer viable, they go the same way as horse buggy manufacturers. Maybe far fewer will be willing to take international holidays every year. Business will seek more sustainable ways of doing the things we enjoy.

How can a market be expected to function fairly with secret information (an externality)? It's intentionally distorted. Pollution, waste and the rest comes with negligible immediate cost, but far reaching consequences to everyone else's freedoms. If all those externalities are priced in, customers can make informed decisions.

It doesn’t matter if we’re willing to shoulder the cost. We bear it whether or not we want to. The question is whether you want to bear the cost in the form of health and climate effects, or in the form of money.

>But who determines the cost? Who amongst us does not produce CO2?

Courts are responsible for determining fiction from reality. This is true whether we're talking about gunshot murder, or climate damage.

Whether you produce CO2 is irrelevant to truth or fiction.

>YOU are the customer if each of these externalities that you are arguing against. Are you willing to shoulder the cost?

You're also the target of the damages. If you think climate change won't absolutely skyrocket food prices, I have a bridge in the Sahara to sell you.
