Could I convict someone for a victimless crime that helped people? The answer is yes. Yes of course I could. I could also have an affair, blow up my car, do a naked tap dance on my boss’ desk, tell my kids that I don’t love them, and finish the day trying to underwater basketweave.
If the laws of the physics does not prevent me from doing something the answer to the question “can I x” is yes. If the question is it likely well that is a much different story.
