Mikefly, if you don’t mind me throwing my two cents in here in regard to your last question?
First, a corporation would not technically exist in an an-cap situation because corporations are businesses with special government protections, and as I’m sure you are well aware, they get granted favors at the expense of tax payers and their competition in many cases.
However that doesn’t mean that here wouldn’t be large and successful businesses. So what would stop them from arming up and taking over their competition? The cost of doing war is expensive. Would you voluntarily support a company that took up arms? What would happen to their overhead and thus the price of their goods or services? Wouldn’t this cause customers to take their business elsewhere? How many of their employees would risk their lives for such a thing? When a state wages war it’s citizens have no choice but to fund it’s war efforts and in many cases no choice but to fight.
So a company starting a war would certainly lose employees, public support, and have increased overhead.
Admittedly such a thing is still technically possible despite the draw backs I mentioned. But let me ask you this. Is the risk of getting cancer in the future an excuse to not rid yourself of the cancer you have now?
