They're saying that the total amount of stolen good isn't an upper bound on things that could be legitimately forfeited, because there's other ways to colors goods enough that they become subject to forfeiture. But that wasn't my argument or point. Like how you put it, it's that the scope of forfeitures is bigger than stolen goods. The comparison is only useful to help give a size of the problem. The critique is in 2 parts: 1, at least a significant portion of civil forfeitures are illegitimate, if not most of them and 2 this isn't a small problem but instead on the same order as stolen property.
