Picture this. Economical collapse and you are in the suburbs or in a rural area where you team up with neighbors. You share duties to protect your small community which include security detail. It would make sense to wear it.
Or, you got stuck at home with wife and kids and a gang of thugs is raiding a house across the street from you. Throw on your armor and make sure you have spare mags.
There are countless scenarios where it would be useful.
you are right. I guess there will be scenarios.
If we are moving and since we have limited weight capabilities ( We are humans, lets say we have to walk 200 miles to our destination and lets also say large scale chit like mentioned above)
we will have to make hard choices on what we are going to take that is going to guarantee our survival.
Lets take one extreme, like the military for example.
Infantry has 3 equipment priorities and 3 problems at the same time.
1-Weight
2-Weight
3-Weight
This was a problem 70 years ago and it is even a bigger problem now.
