I have IRL facepalmed reading this. This comment gave me the equivalent exposure to 10 hours on X/Twitter. Mate, the reason you now have clean air, safe to eat food and drinking water is BECAUSE OF government compelling private behavior.
With your logic we should have just waited for free market competition to kick in for Cocal-Cola and McDonalds to decide on their own to stop putting arsenic into our food or for Ford and GM to produce engines with lower emissions.
The reason we have government compelling private behavior is that corporate interests are more likely and more easily to collude to fuck over the consumer together for profit, than consumers can do the same in order to intact desired change on the free market.
