I understand that most people agree with the above view, and they have what they believe are good reasons to think that. (And no doubt many will reply with these reasons...)
But I don't agree. I don't think that any such forcible takings are justified. If people want (as I do) a government to protect them from a Hobbesian nightmare, let them choose to pay for it voluntarily. Such a government could publish lists of people who have paid, and how much they chose to pay, and maybe with a brief description or statement outlining why. People could then choose for themselves whether or not to have dealings on people on the basis of what they find in that list.
One benefit of this is that you could say, "not a dime from me because you're invading Iraq," or "none of my money may be used to fund executions, drug prosecutions..."
