It was once widely agreed upon that slaves had no rights. Just because something is widely agreed upon doesn't make it right. I would argue that the proceeds of the private trades you engage in are fully yours by right, and that no reasonable case can be made to the contrary.

To suggest that it is not a right is to imply that it is okay for a government to demand that two private parties divulge information about a private trade they engaged in, and throw the two parties in prison if they refuse to divulge this information, or if they refuse to hand over a share of the value they received in this private trade.
