Cheap electricity and convenient transportation for yourself at the cost of everyone else's health, well being and future is something a free market could offer

Cheap electricity and convenient transportation for yourself at the cost of everyone else's health, well being and future is something a free market could offer and I'm not sure why you think I denied that. You fail to demonstrate how more of that free market fixes safety problems. If you are suggesting the normal solution, you will end up creating stacks of regulation to force people into "free markets" for services they should buy to offset externalities such as risk to 3rd parties, which will in turn seek ways to create new externalities to cut their costs. That stack of turtles can either collapse under its own weight and need to pay usury rates or not actually address many of the externalities, or both..
