It's one thing to talk about one's fantasy of breaking the law to protest one's beliefs but actually breaking multiple laws (operating someone else's pots, theft of someone else's catch, illegal retention of crab, to name but a few) but to actually act on one's fantasy enters into the realm of obsession.

No matter what we believe, we must act lawfully. If everyone did what your friend did we would have a war out there. Despite what your friend believes, he is not "entitlled" to a limit of crab.

We may not think that the speed limit should be 50 mph on that back road and we may not like to be restricted to our side of the double yellow lines but to do act otherwise and break the law puts us all in danger.

Your friend and his actions are part of the problem, not the solution.
