Second, Let me head off an argument before we even gets started: Somalia. Somalia is neither Libertopia, nor AnCapistan. Somalia is a land of tribal warlords, each trying to be the government. In AnCapistan, the enforcement agencies themselves would be bound by the NAP (the above law), and so, wouldn't attempt to become a government. Should one try, the others would be contractually obligated to stop them
And what happens when the others don't try because it'll cost them too much money? Ain't nobody there to force their hand, so why bother?
See above for resources. Also, customers vote with their dollars. If you're an ass and are legally untrustworthy, those involved with you from a business sense, those being both the end-customers buying your products products and your suppliers selling you materials, will both start to dump you.
Oh yes, this always works. Except how are people even going to know what evil shit these companies are up to when a different division of the same company owns the newspapers and never prints anything bad about them? You don't even need your little AnCapistan to see the results of this right now. Coca-cola has outright murdered union organizers in Latin America and their products still fly off the shelves. Hershey's and other chocolate companies use cocoa grown by modern-day slaves on the Ivory Coast, and most people don't even learn about that, let alone have a chance to get angry about it. With the kind of corporate consolidation we see these days, you also run into the problem of trying to boycott companies that make thousands of products of every different description, and you know most people aren't going to bother with that.
Assuming people are rational actors and will always look out for their own best interests and those of society is so incredibly naive that it makes my head hurt knowing people really believe this stuff. Like others have said, this is all stuff that sounds nice and lovely in theory, but the second you try to introduce any reality whatsoever into the equation, it all falls apart.
Yes, because it's SO much more profitable to steal from people and get shot on the third try than to deal with people fairly and have millions of customers.
If I have a mercenary army, I don't have to worry about getting shot on the third try or any try. I hire people to take those bullets for me - it's just good business!
(Also apparently even a dude running around with a gun shooting people is a rational actor who always considers the ramifications of everything he does and would never do anything illogical.)
