- Massive ($10-20e12 USD) investment to make a dent in climate change, in the form of automated kelp processing ships AND genetic modifications/breeding to favor rapid growth. There is no possibility of a few artisanal farmers in skiffs doing anything measurable except selling small batches to $4000/jar cosmetics companies.
- Not enough people enjoy seaweed as a food because it's just not appetizing.
- Sequestration of carbon rather than free use of it in the carbon cycle. Pick a couple of underwater sacrificial deep ocean zones or pump liquified seaweed ash and combustion products underground.
