No one owns the air,so what should we do with the people who pollute CO2.People can't say that because the steel company is polluting,we will stop buying it's steel,because eventually you will need it.So the government comes.
People are smoking nowadays,of course it's bad for themselves,but it's also harmful for the people around him which have a huge externality.No one have the right to stop a person from smoking because it's his own will to become a smoker,so the government start to kick in and do things for the whole community:the government can raise the tax,decrease the smoker,and make much bigger social benefit.Now the government enter the market,instead of letting it go.Because there are laws and rules which restrict people and company.This bring the market to a new stage.
