A lot of people seem to think my statement is a tautology, but it's not.

It's exactly my point that not every material is good for its use. Even ones used in the overwhelming majority of cases -- like leaded gasoline. The ensuing environmental disaster shows it was exactly the wrong choice of material to solve the problem.



"It must be good because people use it" is not a good argument.

Even if people use that argument quite a bit.
