I am not legal expert, but from a logical point of view, this does not make sense.
For instance. If I have a transaction history of my bitcoins. Bought in X and paid y$. Today I sell X for z$, then funds that I receive a fully accounted for. The only crime I could fathom is that the buyer cannot explain where he received his $100.000 from.
What if the following happened, if my neighbour sold his car for $100.000 and paid me $100.000 for a piece of paper that has a drawing that i drew on it? Where is the crime? If my neighbour values my piece of paper at $100.000, then who can say anything?
Well, these weren't neighbors.
If instead of a single transaction between you and your neighbor, you were in the business of selling cars, then the crime would be running an auto dealership without a license.
