Ahem...
So prostitution is illegal. If a woman sells her body her and the customer have both committed a crime, correct?
Isn't that a normal, reasonable law? Now I understand some might have philosophical objection to it and somewhat disagree. But has an armed revolution ever broke out over such a law? Would you willing to fight and possibly die in armed revolution in order to overturn this law?
It is not some unspeakable human right violation if a country has a law against prostitution. Some people might mildly disagree with it but I don't think many feel all that strongly opposed to it.
It is a generally accepted fact of life that prostitution is illegal. Prostitution is illegal, yes? So why should it suddenly become legal if you throw in a camera? That is totally arbitrary.
The only reason it doesn't seem absurd is we (or at least where I live) live in a world where prostitution is illegal and pornography is legal. If you lived in a world where both were legal and people were simply used to such, then you would be seen as this horrible, awful person if you suggested making prostitution illegal. If you lived in a world where prostitution was illegal regardless of whether or not a camera was involved and this was simply the accepted way of things, then people would probably be shocked if you suggested legalizing either form of prostitution.
And so we take the arbitrary norms of our times and places and try to imagine that our norms are some type of reflections of the very fabric of the universe, rather than merely the fabric of what is familiar to us.
For example, we are raised to believe in representative democracy. But this is a man-made concept that society worships. We cannot assume that our norms are somehow innate principles of the universe and of the divine. Can you imagine how silly it would be if someone tried to pray to a parliament or a congress in the sky? The universe in its fabric, in its core, in its essence is not a Western representative democracy. In its essence the universe is more like a monarchy.
