I sure hope not. Two sentences by the author dismissing environmental concerns isn't sufficient.
They also list Boston as an example, but Boston's land creation projects ran over cost back in the 1800's, which most people seem to think is only a modern day issue for some reason. The Back Bay was filled-in because the city had already created an environmental disaster out of it. A dam was built which caused the bay to stagnate, and fill with sewage. Maybe a judge should've ordered an environmental impact study be done before the dam was built, which would've caught this. https://historyofmassachusetts.org/how-boston-lost-its-hills...
You don't need to create land in order to have a functioning public transit system, which would address several of the problems the author brings up, without introducing a plethora of new issues.
