That's fair. Though I will say I don't think any single armed approach to sequestration will be anywhere close to reasonable, so exploring any avenue with decent margins, especially if there's any current practical value to it, seems like a smart idea.

What do you mean by "you can't burn it"? It would release some amount of CO2, but as another commenter points out, there would still be a non-zero amount of left over carbon, no?

Well, exploring bad options is a waste of time, luxury we don't have unfortunately.

If you want to go full genetic engineered plants, there are better options out there.
