Yeah no if I know there is an unsecured gun around that makes me feel anything except safe. There is only a very narrow set of circumstances in which having a gun around is non threatening and just walking around in public is not one of those.

Let's take an example scenario: there's someone who cut in line in front of you at the supermarket, upon confronting them they turn aggressive.

Scenario 1 (widespread gun ownership): you have to deescalate or risk potentially getting shot by a person that is very obviously not acting rational anymore. In turn this promotes less civil conduct as brashness is encouraged.

Scenario 2 (limited gun ownership): you can reasonably argue with the person since the highest threat you are facing is a pocket knife, a risk that can be mitigated by simply keeping your distance or an obstacle in between.

So yeah there is no reason to hand out guns like they are candy. They are a tool designed for war and violence and as such have no place just being carried around in public.
