Suppose you are the sheriff of a remote town in the Wild West. John, the man who used to run the town’s saloon ― the only saloon within a hundred-mile radius as it happens ― passed away, and left the saloon to a son of his, name of Steve. However, unlike John, who was never fewer than two sheets in the wind himself, Steve is a teetotaller, and abhors the bottle. So he decides to close down the establishment ― not to sell it, but to close it down altogether, and smash the bottles to smithereens. And he told everybody who’ll listen without shooting him (which isn’t a great many people, but they talk, so word spread and you heard all about it) that the point is to make sure nobody will open another saloon anytime soon, so as to get the townsfolk to stop drinking already, repent their sins, and start living like decent, law-abiding citizens.
Now, just as Steve is about to embark on the bottle-smashing fun, a guy rides in and demands that he hand over some of the alcohol, so that he can open a saloon of his own. Not that he has a building, or personnel, or much of anything ready, but never mind that. And as Steve refuses, the stranger barges in and demands that you call up the posse and put the fear of God into that obnoxious moralizer.
Steve is telling you it’s his booze, and he’s entitled to do whatever he wants with it. The guy is telling you that by doing that, he’s preventing him from doing something that he is perfectly entitled to do ― opening up a saloon that is ― and that since he has no use for the stuff anyway, it’s just mean and in bad faith. So what do you do? Never mind the law. You are the law, and there’s no other to be had. You’re going on first principles here. If you think that Steve ought to hand over the booze this guy is demanding, you’ll tell Steve that he’s got to do it ― or else. Will you?
As you’re thinking about it, and maybe have even come to a decision, the guy reveals that he is Steve’s estranged brother Phil. You hadn’t recognized him, because he’d been away for a while, but now that he’s told you, you know it’s true. A brother. Family and all that. So, does that change your answer? And then Phil tells you that he’d actually helped John collect those bottles. Would ride around all day to buy the finest moonshine in the state and bring it to pops. Steve retorts that not only is Phil exaggerating the extent of his involvement, but John also paid him for what little work he did put in, and he’s got the books to prove it. Do you think it matters? Are you going to investigate just what Phil did and didn’t do, and whether he was compensated for it?
