I said cost be benefits - it’s now clear that the costs of many usages of lead and asbestos outweighed the benefits. I’m suggesting we look at both sides before we make a decision. Doesn’t seem like an extreme position.
The cost and benefits need to be carried by the same people. Right now with a lot of pollution some people have to pay the price for the benefits of others. Or often the whole population has to suffer damage because some capitalists get richer.
