But then there are the Tooks and Brandybucks going out and stealing produce and foraging for mushrooms? Not exactly nobility activities.

Another way of looking at it is that they don't have to work and is using their past time doing crime just for kicks. That kind of dickishness sounds very much like that of the spawn of nobles.

Remember, they are still pretty much children in Hobbit society. Both the Tooks and Brandeybucks hold fair bits of land, it's just their wild kids running around giving the farmers trouble. And of course there's never any real consequences for them beyond a slap on the wrist.
