I don't fully agree with taxes, because of what they stand for and because of the extent they're used for. BUT I will pay them (when I have to) so that my wealth/assets (and those that have families) don't get stolen and so that I don't lose my liberty.
Good points there.
Aside:
I would recommend a few people to read Immanuel Kant on moral worth of actions. It's relevant to this discussion.
