I don't think it's extreme at all. It only seems that way because we've all be conditioned to accept taxation as something normal. But there's no particular reason why that must be so. And, as Bastiat points out, the Law is nothing more than the collective extension to our individual rights, and so can have no legitimate authority beyond what an individual can do. I can't collect money from you under threat of use of violent force, no matter how noble my intentions for that money. Ergo, "the law" / "the state" / "society" likewise have no standing to do so, except "might makes right".
