That, my friend, is all the difference between faith and organized religion, very astutely observed too. Nearly every cult (including three major religions as well, they just got there first and became Really Big Cults) regulates what to put in one's body (from total alcohol abstinence to nearly mandatory pot-smoking), how much skin to show (skewed overwhelmingly towards women, but men have their share too), and - here is your aha! moment - what to do with one's property, be it something relatively moderate as tithe or extreme as Jonestown.
