There’s a nuance here I don’t understand. Hypothetically, let’s say that I choose to purchase some illicit thing like illegal drugs, firearms, someone’s kidney, etc.
I can certainly see that actually having a pound of cocaine would be illegal because that thing is illegal and it is in my possession. But legally speaking, is the act of purchasing an illicit thing itself a crime? If I go on Ebay and buy that kidney, can the cops kick down my door right then? Or do they have to wait for the Fedex truck to show up with the kidney?
Most broadly, in what legal sense can the government constrain my ability to spend my money?
