If you own a large amount of land than the savings add up. Especially if you live 250 years ago (or you want to match the walls from then) when bricks were not produced and delivered in massive industrial processes and large estates were more common.

Even in the modern era the cost is still relevant. Bricks are still pretty expensive.

If I have 100 acres (square), I need ~2.5 km of wall, at ~150,000 bricks for a 1m wall single brick-width wall (deter animals, mark property).

At the online prices I'm seeing ($0.65), that's ~$100,000. If I have to make it all double width, suddenly its $200,000. $100,000 delta is still pretty relevant for a modern small scale farmer.

The difference is people enclosing 100 acres today are either wealthy estates or using non-brick fences for farmers.
