That depends from culture to culture. Some associated it with wildlings or with "uncivilized" Arabian cultures from Northern Africa, while others found it impractical as they were in the military or were in a religious order. Buddhist monks for example shave their heads completely due to their beliefs, while others cut of their hair for army reasons.
So i have an undisclosed amount of candy with me and i decide one day to give it to you, only catch is that i will give it to you in instalments or piece by piece starting from tomorrow all thru until infinity (or when either of us dies). now i don't have an infinite supply of candy but I'm going to give this to you in parts for an infinite amount of time. from this we know that anything finite divided by infinity is zero. so unfortunately you'll be getting negligible amounts of candy just like ysla will get negligible sums of money from mr. sneaky silva.
if mr. silva keeps the balance in his account and it accrues interest over time, EVEN then it doesn't beat annuity for an infinite amount of time. so max is 0.
Vertical Integration is the answer
