If two other people engage in a peaceful, voluntary, economic exchange of some kind with one another, that exchange might somehow destroy me and take away my liberty, by way of some indirect result not connected to that voluntary, peaceful exchange in and of itself.
So I need to prevent that indirect result that harms me by resorting to violence to interfere with that voluntary, peaceful, economic exchange (N.B. I must be the one to initiate violence against other people who only wish to engage in a voluntary, peaceful economic exchange, doing no violence to me).
And not only must I do this. But if you don't join me in support of my violent interference with those other people's voluntary, peaceful economic exchange, then you also are satanic and complicit in the indirect harm that I predict will come in the future if I don't engage in violence against those peaceful neighbors of mine right now.
