There's no way never to have your livelihood in someone's else's hands ever again; the world's too small. Probably the closest thing is growing your own food in a remote area based only on supplies you produce, but that leaves you exposed to acts of aggression aimed at control or destruction of the land.

Your livelihood depends on so many people when you're doing a tech startup (your clients, the organizations running the internet, the government, the army, your neighbours) it's not even funny.
