(how well might current DDGs stand up to a similar full and frank discussion?)
Analogously, how long did the Shire last against a motivated attacker with comparatively little resources?

I'm certainly not making an argument that it has signs of long-term stability.
The shire didn't had nothing that would deserve going out of the way to loot it (at least nothing known).
Hobbits had a sort of primitive defense systems against occasional invasions of goblins and wolves and LOTR mention their skills in the use of several weapons. A few chickens or tobacco herbs simply don't not worth the mess, specially when men were richer and can just buy it.
