IMO the main problem with bans and things is that the people in authority (including voters) often have limited knowledge about what they are doing, and are not affected by what they do. That makes them bad decision makers. When those bills and agendas get pushed there is a strong impetus for them to get passed or enacted because NOT doing so would look "bad". Pushing them through makes it look like "they care", when the exact opposite it true. They don't really care at all because they are not connected to the issue.
It's easy to ban things, it's hard to fix real problems. In Florida, as I understand it, the problem with the coral die-off is mostly due to freshwater and sewage run-off.

It's easy to ban coral collection, it's hard to stop abusing the environment by unrestricted development and poor water management. I was in the Dry Tortugas, and there were scattered and broken pieces of
Acropora skeletons everywhere. Maybe banning collection is necessary at this point, but reforming water management is more necessary. You would think that authorities would consider it important for people to know. The cause isn't even widely acknowledged.
If you go to the Florida Fish and Wildlife Staghorn Coral page they say the cause is climate change, and among other things hurricanes (!????!)

Research by FWC scientists have shown that the spread of the disease is independent of season or water temperature."

When you have such resistance to acknowledging the real problems, much less making necessary changes, you just go and ban mostly harmless stuff, and make innocent people appear like criminals so that you can look good.
