While most cases don't make international news, the sad reality is that ostensibly petty or trivial real estate arguments consume vast resources globally - this case is the figurative drop in the ocean. And really, they always have - this isn't new, any more than your quoted bickering-children example is. The reason is the same reason that 'real estate' earned the key descriptor 'real'. People will literally go to war over two things: people, and land (*some would add religion, but I'd suggest that's generally been a convenient excuse under which lay the truly motivating people+land end goals).
