But to reiterate the important point here: "b) you still haven't shown how any such systems has a right to rule others without consent."
If you have the power, you rule others. There is no right to do so. There is just the power to do so.
Religion is just one more tool with which people can develop power over others. Fortunately today, people can walk away and laugh at this. Religion is the Emperor without clothes. When you quit playing the game, they have no power over you any longer. To walk away from economic power is also possible, but not completely. But you can certainly lessen its power by going "off grid" and dealing with your neighbors through barter and work exchange. Did you know that you are subjected to $1,000 of marketing each year? Thats a lot of programming you have to overcome, but it can be done. Ultimately, like free healthcare, that $1000 comes back from your wallet. Except it didnt heal you of an illness, but gave you one.

Take your power back and quit giving it to them by falling into their games and manipulation.
