Of course I understand that it's a personal choice. It's all about the individual in America, I get it. "It's what works for me" is the mantra of every arm chair forum commando who never actually had to use their guns in combat or self defense. But there are others who have and they have something to teach us.
You say only a fool selects a caliber based on someone else's opinion? How so? Do you think that ballistics is all a matter of opinion? You think that someone basing their ammo choice in order to best save their lives and/or the lives of their loved ones on what experts in the field are recommending and using is a fool? Are you serious?
And it most certainly does matter what our military and law enforcement are using because most of them don't have a "personal choice" in the matter. They have guidelines to follow and have to carry the approved guns/ammo which, coincidentally are not .380's. There is a reason for this and it isn't budget constraints or a lack of knowledge about firearms from higher ups, it's because they just don't work all that well and/or are not as reliable as other, more larger calibers. This is not a matter of opinion but of ballistics, science and street/battlefield credibility.
You're missing the point. You're telling us what we already know. Preaching to the choir.
The OP asked if the 380 is enough. It is extremely obvious that you don't think so.
State your case and move on.
