Many deadly poisons are (or can be made by mixing) household chemicals. Fertilizer has been used to make bombs. Black powder can be made at home.

Guns are not "weapons of war" by default. The obstacle erected to prevent people from buying guns do not promote safety. Crime does not correlate with firearm ownership rates or types of firearms available.

Appeals to fear and popularity are irrational. Do you know what the real trend has been in violent crime over the past 35 years? It was dropping before the Clinton gun ban in the 90s. It continued to drop after Bush allowed that law to end per its sunset clause. It has dropped as states relaxed restrictions on carry. It remains high in two key areas: 1. impoverished neighborhoods with gangs and a black market in drugs, and 2. "gun-free zones."

No misdeeds by others can ever justify anyone infringing on peaceful people. Should crypto or cash be banned because they are "preferred by criminals"? No. Same for firearms, even machine guns. "But what about the children" is the exact same argument used by these book-banning Karens who prefer state violence as a solution to their fears.
