Oh wow I did not know that they require this now - this is somehow amazing because You are actually providing arguments for my side of debate (according to this https://corporate.walmart.com/newsroom/2018/02/28/walmart-st... walmart self regulated itself despite moderate law).
In all You have few good arguments for You thing (which is I assume gun in every household?). I just do not get why anyone would want that. The idea that You can somehow defend yourself without any additional risk is pure fantasy (as they say if you take out gun better be ready to use it) - I believe that one of the greatest inventions of human kind is state/government monopoly on violence. This of course can and actually was abused many times but no implementation of idea is perfect but this does not mean that the idea itself is invalid.
And just to finish I think I must comment on this: >> Poland is not free from violence and cities near your border are being bombed by a murderous dictator. If you want to be defenseless that's your prerogative
What kind of fantasy land are You living that You think that You can actually defend from bombardment, or tanks, or organized military units with gun? You might have seen too many action movies. If by accident You are part of any kind of paramilitary organization that by all means - sure you can try to stop some military man coming Your way but You do not need to posses private guns for that - one armory per district is more than enough to hand out whatever You may need (as it actually was done in Ukraine - the guns were handed out after the war started).
