NPC communities Improvement

What i'd like to see would be that the npc communites can improve and fortify themselves.

It's kinda unusual to me that a community you might run into first this in the beginning of the game still lives in a shack days or months later.

Let them start setting up some beds, maybe a palce to cook/grow food, some fortifications and maybe start having a vehicle in front of their base.

The bases could have a level system. Something like:

level 1 they have started to fortify their base.

Level 2 they are setting up some infrastructure like food and production.

Level 3 they might have active guards.

The bonuses provided from these NPC camps could increase with level as well.

This could open up  a new line of quests where players need to assist with gathering upgrades for these bases and even need to donate/assist with the correct profession(Utilities, Gardening,etc,etc)

I think this would give the worlds we live in much more depth and make the various encampments more than just some random bonus.
