You didn't address the substantive part of my comment. Straightforwardly under the regime you've described, individuals are not only prevented from, but can be actively
punished for:
1. Using mathematical formulas to demonstrate facts, such as pointing out that speed can be calculated by distance over time.
2. Pointing out how a red light camera fails to meet required implementation details.
3. Pointing out how a bridge is unsafe.
4. Pointing out that an expert witness is glaringly wrong.
5. Comment on the details of a public proposal.
Nutt's case is analogous to 3. Nutt did not design the stormwater system. He is critiquing it for a poor design. In an open society, that is everyone's right. The court can choose to find his reasoning lacking or simply non-understandable, but he shouldn't then be getting attacked for having spoken his opinion.
Errors and disagreements are common in engineering, as in any art, and so any honest engineer should be worried about criminalizing debate. Given enough eyeballs, all bugs are shallow.
Licensure boards can be notoriously aggressive, which is why this case is getting attention. Furthermore, state-chartered entities are commonly over scoped because they're really just extensions of the state executive, with only court cases to push back on them. Your argument from status quo is uncompelling.
