“The Shire at this time had hardly any ‘government.’ Families for the most part managed their own affairs. ... The Thain was the master of the Shire-moot, and captain of the Shire-muster and the Hobbitry-in-arms, but as a muster and moot were only held in times of emergency, which no longer occurred, the Thainship had ceased to be more than a nominal dignity.”

Sounds like night-watch libertarianism that had declined to something even more minimal. Which ironically was easily run over by a smooth-talking old man with a broken staff and a pretty small bunch of ruffians. You had one job.
