> If there's a specific regulation that can be shown to be doing more harm than good

In Massachusetts you can't clear shoreline. Specifically, if you buy waterfront property on a pond / lake, you can't clear the shoreline to make a beach in your backyard. You can only use what used to be there before the law was passed. There's even restrictions on building close to shorelines, so if you want to build, you need to find an existing building and renovate.

Now, I'm not a wetland expert, so maybe someone will chime in and tell me why every inch of freshwater shoreline must be undisturbed. But I like freshwater swimming and suspect that we can allocate some space for human recreation.
