So you'd rather let the ocean come in and destroy the buildings and the tourism industry along with it?
That's fine if you think that, but I'm sure you can see that that is not a viable alternative for the government to accept. (Unless they go broke).
I'm simply saying if you have a better alternative to what they are doing that would save money or do the job better exc exc. Do something to get the word out. Maybe they are doing this every year because they just don't know any better....
There is always posts complaining about how dumb they are for doing this but I've never seen anyone with a better idea who said they tried to tell the government the better idea. If you have a better idea put it together and use the forum to get some people behind it....
