It is about as logical as prosecuting someone for spending 'profits of selling some cannabis' on bread.
That some money (mine) has a different inherent quality than other money (yours)... and that someone (govt) has a (a) the right to know the difference (b) define that difference and (c) the circumstance in which that arbitrary difference is applied.
It leads to the legal assumption that property including 'cash' can be guilty after the fact, or could be/might be 'suspicious' creating an unwarranted 'need to police'.
That 'we already do it for....' still doesn't make it right, sustainable, good or civil.
