You want to live in the stoneages again, don't you?
Without any rules, we have anarchy. Then I guess we don't need a police, do we? We don't have rules. So if I murder someone on the street, its perfectly fine. People can take my property, because without rules "property" doesn't exist. Then we don't come to "people live in peace and harmony", but to "people live anarchy and take whatever they want and do whatever it needs to survive". Complete society would crash. You say that science matters, do you think science would evolve from anarchy? Do you think we would have a single computer when we were living in anarchy?
Taking religion into your argumentation is very clever, since this board is mainly atheist, so this could bring you a couple of lost souls that agree with your opinion. It is still just stupid. Run around and scream for anarchy, one day you'll grow up and see that it is the wrong approach.
