Why shouldn't the government lock up a criminal that does so much damage? And what does it have to do with you? Does it matter that he is your brother? Are we supposed to judge you by his actions? Are you saying we are lucky to have a benevolent dictator such as yourself?
I've essentially presented the argument that gets you from either historical materialism or utilitarianism to communism/socialism. Here's the rest, laid out more explicitly:
.1 If my brother and I were one person, it would go from illegal to legal but nobody's balance sheets would change.
.2A (use this one if you like historical materialism) Laws and ethical notions are constructed because of balance sheets. Why, then, don't we change the law so that the apparently arbitrary distinction goes away?
.2B (use this one if you like utilitarianism) There's no basis for law beyond utility, and it's obvious that both cases have the same result. Therefore, there's no basis for a legal distinction.
I've never figured how to get out of this argument, except by making private property a fundamental right. That sounds a lot like objectivism, though.
