That's not exactly what I'm saying. I'm suggesting that a lot of the infrastructure that businesses depend upon is provided by the state. I'm thinking about property rights, currency (at least until Bitcoin, but still to a very large extent), roads, etc. I don't think the market couldn't do it, but for a big part it isn't incentivized enough to do it (example: a road between two poor neighbourhoods, clean water/electricity for everyone, even if they live far from others).
