Growing and delivering the seaweed is among the smallest problems to solve. The animal agriculture industry already involves growing and shipping billions of pounds of feed. This is just a different type of feed, and it is seemingly only needed in tiny quantities, so it will be dwarfed by other expenses related to raising cattle for consumption. The only thing missing is a profit motive...without taxes and regulations that internalize those external environmental costs, there's no motivation for cattle producers to add even this small cost.
