Idk what was even said... How many elements are copies of dust? Sand? That turns into glass, hardly a copy. Broken metal? That would be conductive, good to make bullets. Broken glass? We need it for sand! Salt? We need it for saltwater! Stone and concrete? Good for a bunker layer! Am I missing anything? Not really. We aren't copying dust, and we definitely aren't being swallowed up by it.
Neospector I see your point but as more newbies come into PT. The more requests will be asking for dust's elements. And possibly one of the coders is gonna go f* this and add them. And then we'll have a web war on our hands and we'll be called a "paper" as FF50 said.
