What's funny? The idea that a person isn't subject to taxation or laws simply because they don't vote. Try holding up a bank or refusing to pay your federal income tax. Send them a letter explaining why it's ok for you to do these things and see what happens.

It's not a contract, it's a process that contiues and changes. If you remove yourself from the process, you only remove yourself from the process and the decisions made. It sounds like this whole process and the concepts involve seem foriegn to you anyway.

As to principles vs 'doing the right thing', it comes down to compromises between ideals and reality. A person may believe in communism, and yet still has to work for a living.
