Answering any question of "should" implies a moral standard giving direction to your choices. I don't know what your overall moral system is, but I do know that the ethical system you prefer (i.e. the subset of morality concerned with the right and wrong ways people should deal with one another) comes from the Non-Aggression Principle. So some of the questions rattling around in your head are most likely some of these:
1. Can you afford to "take the job" without accepting the salary that goes with it?
2. If not, are you willing to accept the salary, knowing it was extorted from unwilling folks like yourself?
3. Is the fact that the same "taxes" will be extorted whether or not any of it goes to YOU, relevant?
4. Are you willing to take an oath to uphold the Constitution -- including the powers "granted" to Congress which no "normal" person possesses (i.e. tax, regulate, declare war, yadda yadda . . .)?
5. If you would prefer not to make that pledge, do you have a problem with lying under oath?
6. If you feel that no "good" person should have to put up with all that crap . . . is it inevitable that only "bad" people will be willing to run for public office?
7. If you believe that "public offices" should be abolished, rather than staffed by ANYONE -- is there a way to achieve that goal without getting inside the evil machine and taking over the controls?
