Samapple31,
could you please define "peaceful" !
You don't do any harmful thing against animals or plants ? How do you eat when you don't harvest plants at last.
The peaceful difficult at the storyteller ONLY disable Raid's and such incidents.
But you still encounter mad animals and how do you want deal with it, beating with fist against it ?
You shouldn't be so focus on weapons, any tool is a weapon, so just see weapons as tool too.
Do you want forbid beer and wood log's too, because they can be used as weapon ?
