Which is why they are very popular in the less densely populated and large lot size areas of the English Country side. By the time of the New World, fast population growth meant the economics of brick production wasn't feasible and copious alternative methods were easier (wood/picket fences, wood studs+wire, chain-link or wrought iron/brick + iron). All less long lasting, but cheaper, quicker and easier to install with almost the same benefits (fencing of pets + livestock, property demarcation, security). Which is why you don't see them nearly as often outside of Europe (Asia having used their own alternatives better suited for their environment and needs, Africa having had New World techniques used during colonialism).
