It's a bit misleading though. Government affects us in ways he doesn't necessarily think of, such as negotiating passport and import / export arrangements with other countries, mediate border disputes and obviously they're supposed to be able to protect us in times of war via the army.
However, having said that, I've always felt that a country would be more efficient if government itself was a private company. Where ministers get hired and fired on the basis of work performance and credentials. They can be externally audited and the President would be like the CEO of a company.
