Nice title. Well, here we have an anarchist. If you've never seen one here it is. Right off the bat let me say that I'm not an anarchist and I don't agree with the premise of the article.
That being said, I will direct my comment toward attacking only the article within the bonds of the set discussion.
The main issue is that you haven't thought out all the conditions, yet. The jobs are only immoral if you actually are applying force in a situation where non was needed.
A) Just because you are a solder in an unjust war doesn't mean you are taking lives unjustly. I'm sure there are many people in the military only killing people that should be killed. Police is a little harder to defend because I don't know the job well but there may be some that are only applying force in situations where it is needed. Although, I think most traffic stops are unjust.
B) You are leaving out the politician or teacher that is not commanding force. Politicians can hold office and only be there to create laws that give you freedom instead of taking it away. The same for teachers. You are saying that all teachers would report truancy when some of them may not be following that order.
C) Okay again going with the premise that this is stolen money, it absolutely is immoral to accept stolen goods. It creates an economy. If no one trades in stolen goods, there will be no economy for stolen goods. If you are knowingly taking stolen money it is immoral.
Illegal drug trade in the US subsidizes (drug) cartels that kidnap and murder. If you take away their economy of drugs, they lose their funding. (This is one way the war on drugs is so immoral.)
