Yeah, if you don't cross state boundaries (or even leave your village) like most people at the time the extent of the fence isn't really that important. Paris had substantial stone walls to enforce its own tax boundary at one point; since bits still exist plaques commemorate its existence, but I'd be surprised if the average Parisian thinks about the line of the wall much. The bit that got enshrined in the popular consciousness at the time is how much they resented the authorities levying the tax, and it appears that likewise the tax itself - not the implementation detail - was on Indian nationalists' grievances about British colonialism.
