You are half right, but because you were only half right, you came to the wrong conclusion. By your own admission, sports fishing brings in more revenue. Now why is that? BECAUSE SPORTSFISHING CREATES A MUCH BIGGER ECONOMY FOR FAR MORE PEOPLE GIVING FORE MORE PEOPLE A CHANCE TO SHARE IN THE ECONOMY THAT THE OCEAN BRINGS. And yes, the result if more tax revenue, but like Reagan tax cuts, the primary reason to do it is to create more opportunity for more people.
It appears to be "creating more economic activity" by artifically making it less productive. It's like banning bulldozers so that you can create more jobs for people with shovels.
