Good to see at least someone read and understood the article (not that it was hard to understand).
The whole point is pure urban sprawl without any trees is definitely not a good thing for many reasons (i.e., poeples health, appearance of the city, etc.) thus why there are codes regulating things such as greenspace and trees. However half assed following of the regulations generally costs as much as actually following the rules but leads to shitty appearance and dead useless trees typically very quickly.
