What if civilians had extreme firearm freedom, but with mandatory responsibility and training?

Hi everyone, I wanted to explore a hypothetical scenario: Imagine a society where civilians could legally own a wide range of firearms, including historical weapons, SBRs, PDWs, and even certain extreme mods (like full-auto on compatible guns), but with strict conditions: Mandatory training – from childhood, including safe handling, CQB simulations, and proper storage Family involvement – parents actively teaching children about firearms responsibility Safety culture – strong focus on discipline, secure storage, and responsible use Community oversight – clubs and online communities promote education and safe practices Legal limits for misuse – any criminal use leads to severe consequences The idea is maximum freedom paired with accountability, so citizens could defend themselves and enjoy firearms as part of culture and sport, while society maintains safety. My questions for the community: How do you think this would affect crime rates and public safety? Could such a culture realistically develop in countries like the US or Brazil? What would be the main challenges in creating a “responsible freedom” firearms society? I’m curious to hear your thoughts!
