He doesn't start out by saying "we have to start looking at most taxation …" so he is including all taxation as being evil. However (in my opinion), he is tacitly acknowledging that, though evil, some taxation is necessary. If we prefer a limited representative government to anarchy, for instance, we need to pay those people who represent us. If we want our government to be able to enact treaties with other nations, say one which will obligate them to respect copyrights, we can't expect our President to cover his own travel & accommodations when visiting those countries. But beyond the most rudimentary costs of maintaining that limited government, "the less people are taxed, the better."

@Wordmage I certainly agree that often taxation is evil and that we should limit the amount of taxation as much as possible. Personally, however, I don't think taxation in and of itself is evil. But there is much difference between our views at the end of the day.
