Lobster isn't exactly a staple food anyways. I have it maybe twice a year in a sushi roll or sandwich, which is probably more often than your average North American.
I know plenty of people in fishing communities that eat lobster at the same rate you may eat hamburgers or pasta. One of my close friends growing up had a lobster fisherman father, and they ate it once a day. That and deer/moose meat was the staple food.
Edit: The goal of this comment was not to say that this is incorrect, I am for this change. My goal was just to say I feel there are places where it is staple. That's it.
Lobster is a food item, just because it is now treated as a special food item on special occasions does not mean everyone does.
Lobster is not a staple food for the majority of the world's population.
It used to be prison food.
If its a wild caught species there is very little expectation to factor that in. Perhaps you can bifurcate the model between commercial and hobby fishers but not much more.
