if your need more convincing and don't mind mild spoilers,
The ability to make gunpowder from bat poo is recognised as dangerous by the antagonist, so he tries to keep the protagonist (who knows how to make guns) away from access to bat poo. The protagonist exploits this to gain the upper hand. Because there are military technologies far more dangerous than guns that he knows how to create, and misleading his enemy can only help.
I, too, have seen Doctor Stone
I haven’t. Should give it a watch I guess.

Thanks. It’s on my queue now.
I found the bat facts when I was looking up the history of fireworks.
