Use of money should not be criminalised. Theft, murder and kidnapping are already crimes. You do not need to make the use of the money from crimes illegal. The use of money can form evidence in a criminal prosecution, but the making the use of money alone criminal is a short cut to conviction, which places such a burden on the financial system as a whole, that is simply not worth it. https://www.tandfonline.com/doi/full/10.1080/25741292.2020.1725366#d1e146
