Faith in God is the biggest and in fact only threat to total state control. It gives the human being a separate moral identity and a separate allegiance, and this is why the state - when it’s on a rampage, as it is in Communism or Nazism - does everything possible to destroy religious faith. Faith makes one free.
Interestingly, in my mind, one of the biggest threats of Islam is that it is the only truly theocratic system that has ever existed on a large scale, that is, where government is (ideally) carried out by the clergy and where religious law and state law are identical. In other words, it achieves what everybody from the French revolutionaries to Hitler tried, and essentially neutralizes even faith by making the state into the voice of God. Islam’s gradual merging with Communism and extreme left-wing movements is no accident, because Islam is very collectivist and authoritarian by nature, and at the same time gives these totalitarian systems the final thing they need to exert ultimate control, that is, God (or at any rate, a deceptive claim that they represent God). Essentially, of course, they are all Luciferian.
50% accurate.
Islam is authoritarian. It is not collectivist, as Mohammed explicitly approves the institutions of private property, profit, etc.
In a truly authoritarian state, of course, the individual has no rights as against the state, so private property has no meaning once you incur the wrath of the ruler. Only those who fly below the radar are safe. A major reason why in traditional Muslim societies one hides rather than displays one's wealth.
