Judging from the article, the intentions of the beavers aligned with the intentions of people. Yet that is not to say that the requirements are the same. Even if you ignore things like environmental assessments and safety (both during construction and during its lifespan), neither of which are codified by beavers, you still have things like maintenance. Beavers will only maintain a dam for as long as it serves a purpose to them. Once it does not, it is left to decay. Human society just doesn't live like that anymore. There are both short term and long term costs to consider. That wasteful government will likely mitigate some of those costs.
