This is just how humans are. You pick something you like and then you support it fully. Rewind time to 10,000 years ago or whatever. You're out distance-running animals to exhaustion, and your friend trips and breaks their leg. You stop the hunt and carry them back to your village. You go out tomorrow and hunt without them, and give them some of the food you caught anyway. Someone says "man this guy is lazy, let him starve!" They are ruthlessly taunted for going against the group. The broken leg guy recovers and society moves on. It didn't have to be that way. You could have watched someone break their leg and say "that sucks bro, enjoy dying" or you could have gone along with the "this guy is lazy, let him starve!" cries. Both are rational actions that many other species would take, but for humans, evolution didn't favor that. (Probably because an adult human is a pretty big sunk resource cost. 9 months of gestation to have 1 kid!)
The end result is that we still have these instincts. We want to belong to a group to receive its protection if something goes wrong, and we want to support our group so the members know they're getting the protection they crave. The end result is that in a world without life or death consequences at every turn, we naturally apply this to shit that doesn't matter like rocks. Same brain, different problems.
I'll also add, this is what science is. People say stuff. Other people test it. Everyone shares their results. Is there a better system?
It's the choice you make; 'it's just how I am' is a weak defense. It's surprisingly trendy to say bad behavior is inevitable. Human's have been biologically the same for ~300,000 years, but our behavior has changed dramatically. Behavior in different places right now varies greatly.
Also, is there factual or expert basis for this theory?
