Why is it better not to use metals to create static electricity?

Static electricity basically refers to an electric charge stored on a location, unable to move. It only moves when it finds a way to be transported, by a conductor. Commonly it can be seen discharging abruptly, in an uncontrolled way, when the charge level exceeds the insulating limit of air. Like on lighting or when taking out a sweater. Metals are conductors, hence it is hard to create a charge on a medium that facilitates its movement.
That is why a wool sweater, a plastic based carpet and dry air are static charges friends, because they are insulators that prevent charges from moving and neutralizing.
Even bad conductor like leather shoes can prevent static charges from storing, while plastic sneakers an sports pants give you a static shock.
