The only result of not paying taxes is that you will go to jail. No one in the government will care about that, so that seems to be a rather pointless way to protest. Moreover, if you are in prison, the worst ethical lapse would be against yourself: you will have created a very bad situation for the rest of your life, and it would be much more difficult to work on yourself effectively. So, if you want to work on your ethics, think about it in relation with what your BEING needs you to do. Real ethics are about the relationship between the soul and the spirit. If you have the ego alive - such as fear, anger, pride, lust - that is a far worse ethical breach than paying taxes. Your Being does not need you to change the government. The Being needs you to work on yourself. Eliminate your egos. Be kind, gentle, and helpful to others. In this way, ethics becomes an immediate, practical, achievable, effective way of living that measurably impacts you and those around you.
By the way, if you do go to prison, you definitely will be "handing over our decision making process to others."
