I think commons like fish in the ocean and air quality in cities should be priced. If of you fish its not free you pay to the country whos fish you fish. If the fish is extinct or heavily MSC on the red list the price is sky high in the millions this is to protest the species and our eco system so future generations can enjoy that fish.

By pricing eco systems and sustainable common resources. We avoid tragedy of the commons where few extract all value from common resources for free.

Ie such a new economic system would price the rain forest at its true value to humans and earth eco systems.

Carbo emissions would also be priced differently.
