You can think of it as similar to a human taking a cheap charcoal tablet with their food to reduce flatulance. They will not take such a tablet until they are aware they have gastritis. When enough pressure is applied the solution will be implemented.

Only a small part of the animals feed needs to be seaweed and thankfully it is one of the easiest and fastest growing organisms on the planet. So it’s extremely cheap for the industry to adopt the solution when compared to facing losses related to carbon taxes and loss of market share.

Sorry, edited my post while you were replying.

Your underestimating the amount of food cows need to eat a day and likely overestimating global seaweed production in relation to even supply only 1% of cattle feed.

89 millions cows in the US alone eating eating 20+ pounds of food a day is 890,000 tons or nearly 325 million tons per year. That’s per day. Global production of seaweed was 358,200 tons in 2019. Only about 11% of what would be needed to be included in 1% of feed of every cow in America. And that wouldn’t leave any seaweed to be used for any of its other uses or the millions of other cows around the world.

Seaweed grows very quickly. The historical production was much higher a hundred years ago, but there's been relatively little need for seaweed in recent decades. It would not be hard to farm more of it, if there were demand.
