Why do you think that a lot of people want "small government"? The state/government is by definition in those "commons".
Regarding examples, they're countless. Think of petty tyrants fighting over the remains of the Byzantine Empire just as about the Ottomans were about to conquer it. Almost every falling empire had this behavior going on, selfish people "getting theirs" just before the fall.
It's human nature, unfortunately.

But because the government/state is ill-defined and shared, it can be abused and it's much harder to do anything about it.
Private property is selfish but efficient and clearly separated from the rest (in general) while public property is altruistic, not that efficient and generally not that well delineated from the rest.
I love evolution of USSR for this reason. First the masses took down Tsarist regime to take property of the rich. Then masses took down Soviet regime to privatise the property. Both events happened because life was shit and people were looking for a quick way to live better.
Do you have any arguments to believe in the other option?
A) be poor now
versus
B) maybe face the collapse of global civilization in 40 years.
They'll chose B) everytime.
