> Out of curiosity, how would one deal with a chemical plant poisoning groundwater wells, without laws and regulations? No clean water laws, no crime.
The market would develop technologies, people would move, or would boycott the polluters. A chemical plant that poisons groundwater wells wouldn't be in business for long in a free society.
Chemical plants, strip miners, coal plants, etc. poisoned the soil, water and air for many decades without consequences in America before the environmental movement of the 60s - 70s.
If an Rayovac battery plant poisons the water in Ohio (burn on Cuyahoga river), the locals might boycott it, but the batteries shipped to New York and California would be cheaper than those of a competitor who spends extra not to pollute. So Rayovac makes money from those outside of the area it poisons, with nothing to stop them.
If enough companies do this, "people would move" doesn't work, there's no clean water and air left to run to.
