The reason you cannot ban weapons is because anything could be a weapon. A rock, pencil, barb wire, glass, car, etc.
I know what you mean, but there’s always nuance, a limit, when it comes to things like this. Just because you can use anything as a weapon, doesn’t mean everyone should have access to everything. Rocket launchers? Bio weapons? Nukes?
Banning weapons wouldn’t make crime vanish. Also the whole point of crime is that you break the rules to do it. Your strict rules would just be broken by certain people hence creating the “crime”.
Similarly, that doesn’t mean we shouldn’t try. If there’s no need to ban things because criminals will do it anyway, why have laws at all? Murder, rape, assault etc.
Ultimately, societally, we attempt to come to a collective idea of what we think is “right”, and then attempt to enforce that.
Initially most are very straight forward, like “don’t kill people”… But then the deeper you drill into it, the more complicated it gets. What if you accidentally kill someone? You give them something they’re allergic to without knowing it? Should you get life in prison?
I feel like arceus was waaay more dialog heavy? At least on the early game, I haven’t completed ZA yet.
