Externalities and long term planning are known issues. They can be managed by the government to some extent. Really it all comes down to managing incentives. Obviously capitalism isn't perfect, but I doubt there is a better alternative. Any other system will have the same issues and complexities. Even trying to solve issues with government like I did above isn't necessarily better, since governments create their own messy web of incentives and complexities.
