What is the great dragon which the spirit is no longer
inclined to call Lord and God? “Thou-shalt,” is the great
dragon called. But the spirit of the lion saith, “I will.” – F. Nietzsche (‘Thus Spake Zarathustra’)
What is a government? It is a group of people who claim the exclusive right to initiate the use of force over other people (citizens) in a certain geographical area.
What are parents? They are people who had sex and had children, and claim the exclusive right to “take care” of them.
Is there a difference between a situation where you feel obliged by people such as “the government” to do certain things for them (say, pay your taxes), and a situation where you feel obliged to do certain things for children? No. They are both obligations that have no rational justification whatsoever.
You may baulk, and be very offended at this claim. But the truth is that you cannot explain why it is that you should take care of your biological children (or pay your taxes). You just feel is “bad” not to… And this, I submit, is why all the bad in the world exists.
