My only rebuttal destroys itself due to receipts (ie paper trail).

If you unknowingly receive stolen funds in cash for goods or services, you may never be found out & would have no idea you were part of/a recipient of stolen property. It is gone & untraceable if the culprit refuses to talk.

Now if they used credit cards, debit cards, or checks, then those could be traced.

We are in uncharted legal territory & I pray the courts agree with this common logic you laid out.
