This piece's purpose wasn't merely to provoke thought and illicit discussion, it was proposing that a certain type of governmental spending is wrong all the time. As you said, its a philosophy. But, since your proposing this as merely a re-evaluation of spending, I'm more worried about the government's domestic pork-barrell spending than I am about sending some aid to help folks who have the stench of rotting flesh fresh in their noses after a natural disaster.
Maybe its purpose was to target a specific type of spending. But, that does not mean we should not view it as thought provoking. It is also important to understand the framework the author was coming from and that many people (to an extent myself) feel that governmental taxing and spending is wrong and against a set of values.
Furthermore, this article should not be used to attack Ayn Rand or the objectivist philosophy, particularly if the context is not understood. Even though the article is in poor taste.
But, we do have some common ground I would much rather see tax money going to aid those who are suffering than something like economic development.
