You could make that case with some examples, but even then, the metaphor overwrites the reason why governments are formed - for the public good (and the protection of personal property, if you are a fan of John Locke). Thus, governments in your metaphor lose their actual purpose.
This ultimately typecasts actions that a government does, into business actions. Even though some of them would make absolutely no business sense. For example, why would a country raise tariffs or raise trade barriers? This would demonstrate weakpoints in the metaphor that other countries are clients.
A more extreme example would be where a country starts to kill people, by going to war with another country, or killing it's own people due to political upheaval. The metaphor really breaks down in that case. Businesses by and large, don't go and kill people intentionally. Obviously there are some historical and modern examples (Chiquita comes to mind) but I don't think that "Killing People" is in anyone's charter.

Money isn't the only way to represent wealth. The ideal government would ensure proper infrastructure(justice, defense, interstate transport) to the country without concern of profiting from it & for the benefit of all citizens. Money goes in, "shareholders"(citizens) earn dividends based off the infrastructure/programs they get back.
For example, why would a country raise tariffs or raise trade barriers?
Why would Verizon put an early termination fee on a contract? Is it because the customer benefited from a subsidized phone, kind of like how business benefits from subsidized infrastructure?
