You are not considering that not everybody can know how everything is produced.

I am more than 30 years into this life and don't know exactly how many things that I buy are produced, how the resources are gained, how far parts were shipped, etc.

On top of that companies go far lengths to hide things that would have a bad public feedback. They even do research only to sow doubt in science. And they print fake green labels and proudly advertise with it.

That's why ideally the government steps in to bring transparency and safety for their citizen.

But guess what? Companies are paying nice money and other benefits for politicians to be able to lead the customers by their noses.
