It’s one, but you aren’t supposed to build that close to the wetland. Like a drain in a house, just because, you should always want water to go somewhere if its on the floor else would have long term problems. Part of the reason street roads are not flat.
The image is the equivalent of choosing to build a house on low tide. and wouldn’t realistically happen.
Is it the real reason? Or somebody just made it up? Because for sure there are engineering solutions to this problem.
There are a couple of great “practical engineering” videos on the topic of you’re interested:

There are cities built on top of former wetlands. And they are fine. Sure, a proper drainage required, and sometimes dam/barrier, but it is doable.
