I agree it’s a problem for the entire surplus to go to the seller. But that problem isn’t impactful people getting rich. It’s that if the certs are too expensive there’ll be too few buyers to clear the market. So I agree that payouts should probably be tuneable. If you want the actual impact of a project to still be known, then you could have the “percent of impact purchased” be the tuneable parameter, if buyers aren’t too sensitive to it.
