No thanks. I don't see how the "flywheel effect" is possible without making several assumptions. The most glaring is that decreased supply equals higher price. Markets don't always shake out like that, so lets not ignore those other forces. This feels more like increasing a tax by 20% with the hope that DEC price reacts accordingly. Doesn't feel like a slam dunk to me.
Further, couldn't the same goals be achieved with a 3% take/2% burn split but on a slightly longer timeline? Or some other combination that adds up to a fixed 5%? Personally, I'd be more open to the whole idea if it included the benefit of having no forward facing change to the average seller.
