The difference between Paypal and real life is that Paypal works with arbitrary laws they set up, and real life works with the laws of physics. You can prevent fraud on the Internet by doing tricky filtering. You can't prevent someone from stealing a sandwich at gunpoint by rewriting how the universe works.

Enforcement is not perfect, but that the police can punish the armed sandwich thief in principle is already a deterrent. It is common knowledge who in this situation would be in the right. Compare with government-free world, where to determine who's right we'd have to make our security companies get into a firefight over it. And they'll probably decide that fighting isn't in their best interest and shoot us instead. They can always find more customers.

There is very little reason to believe private security providers would resort to "firefights" to resolve conflicts. This is an incredibly expensive and undesirable solution for customers.

Go back ten years and have a conversation with someone about a private taxi company that uses technology to operate outside of existing regulations. You would hear outrageous claims about murderers, rapists, and thieves using the system to exploit customers. Of course, Uber drivers can and have assaulted people, but it turns out there are all sorts of creative solutions and private incentives that undermine these outcomes. Fortunately, the future does not lie in the hands of the uncreative people of the past and present. It's the people who can actually envision and deliver solutions--people like Kalanick and Camp--that determine the future.

That's why they'd shoot the customers and get on with it :P.

I'd go back 10 years and I'd find multiple companies already doing the thing Uber does now (sans app, because there weren't app back then) - except they were doing it legally and weren't sociopathic about it.

People who envision and deliver solutions with no regard to anything else than their personal profit surely could determine the future - but it won't be a future any one of us would like to live in.
