Coming from the angle of competition in governance, I think you might be mixing up a lot of stuff. A joint stock corporation which is sovereign is trying to compete in the wider world for customers , i.e. willing taxpayers.

If the people desire the values you have mentioned then the joint-stock government will try to provide those cost effectively.

Clean Air and Immunizations will almost certainly be on the agenda of a city government

Biodiversity will be important to a government which includes forests in its assets and wants to sustainably maintain the same.

A free marketplace of ideas, free education and social safety nets would purely be determined by the market for people. Is it an important value enough that people would not come to your country and would go to another? if it is, then the joint stock government would try to provide the same. If not, then they wouldn't.
