I'm not contesting that there are documents and laws, including the constitution, that say the government has the power to tax me (and others). I'm pointing out that I wasn't a part of creating those laws and I never agreed to them. In other words, if paying taxes was optional - I wouldn't pay.

At least, I wouldn't pay the amount I currently do. I might pay 1%-2% of what I currently pay. I think some of what the government does is valuable but most of it isn't valuable and lots of it is immoral.
