Medieval robber barons most often imposed high or unauthorized tolls on rivers or roads passing through their territory. Some robbed merchants, land travelers, and river traffic—seizing money, cargoes, even entire ships—or engaged in kidnapping for ransom.

I mean, we have a kind of tentative re-implementation of this in the US/Iran fight over the Strait of Hormuz. Also, with the vision of the Network State professed by Silicon Valley elites.
