X got the drugs from somewhere. At some point, someone paid someone to get the drug. This enables Y.

If I want to buy a nuke, but one is not available from a legal seller, does that mean I am not responsible for paying an unscrupulous seller to furnish that for me?

> Also, you can get locked up for smoking weed that you grew yourself and had no intention of selling. What of that?

Where did you get the weed plant? Last time I checked, weed doesn't magically sprout in your hydroponic set up (and I'd know).

I buy guns. The gun lobby, funded in part from gun manufacturer profits, fights laws that prevent mass shootings. Am I enabling mass shootings?

Yes, especially if you're buying guns for recreation. If it's for survival and you live in the middle of the wilderness, perhaps you can make a case for it.

Oops, was that not the answer you were trying to bait?
