Why do you think Christians and Jews and Muslims believe that Adama covered his male organ with a fig leaf?
Why do you think most of the civilized world covers their sexual organs?
They believe it for the same reasons as you do. They do not see understandings of today within context of history.
Go to older versions of religious books, you will see that what one time was "apron of fig leaves" have become today`s understanding as you say - A fig leaf.......
The Latin Vulgate:
et aperti sunt oculi amborum cumque cognovissent esse se nudos consuerunt folia ficus et fecerunt sibi perizomata
And the eyes of both were opened. When they might'd recognized themselves to be naked, they stitched fig leaves and made coverings for themselves.
NB! In the Greek-English Lexicon by Liddell and Scott, perizoma is cited in a proverbial expression meaning to "practice an art with the apron on, i.e. superficially
"Why do you think most of the civilized world covers their sexual organs?"
Such questions makes me uncertain if a common ground for debating exist. The civilized world... Bah! Humbug!
Loincloth are not, will never, and have never been trait of the civilized world as you defined it.

I could go on and on, but point is proven.
And if there are wonders to why the covering of sexual organs are important, the answer is easily seen by rephrasing the question from a more objective perception.
What is the most fragile human organ concerning personal health and social health?
Again I can nothing but to advice people to try at their best ability to perceive the world in context with history. And history predates the defined date: Year 1.
I write this not to protect any religion, because I find any religion more or less similar to any other instrument of control. I write this to protect objective knowledge being replaced by another set of beliefs founded on old paradigms.
