No, it very much should not be. We have an existing sort of crime for knowing participation in that kind of thing, it's called being an accessory.
If someone buys, let's say a bike, off an online marketplace, and it turns out to be stolen, they're out the price of the bike. It never belonged to them and gets returned to the owner. But it must be proven that they knew it was stolen for that to qualify as accessory to theft.
If you make any action which has the effect of obscuring evidence of crime, regardless of mens rea, into a crime, you will end up prosecuting innocent people. That's why this legal doctrine works the way it does.
