Naked in Public

Photo of a naked lady taken in Makuhari. I've always wondered what the philosophy is behind allowing a naked statue like this iron lady to be placed in public for all to see - including kids.

Thought it would be interesting to discuss why most folks don't make a fuss when they see stuff like the iron lady in public, and yet like to comment and send me mail about the "NSFW" photos of naked figures on this site.

Both Sonsaku and the iron lady have been sculpted by hand and are naked - the iron lady is actually full frontal naked. Sonsaku does indeed have bigger eyes but should that make her more NSFW than the statue in public?
Some may say that Sonsaku is the sexiest out of the two but shouldn't that be a matter of taste?
Is it OK for the iron lady to be in public because she is made of iron just like the mermaid statue in Denmark?
Or is it because Sonsaku has been painted?

Was just thinking about all those oil paintings of naked women in galleries and the statues of naked men in Italy - could be because the iron lady is considered as "art" ? But I personally consider figures like Sonsaku to be works of art too.

Would you mind 1/1 scale statues of naked Sonsaku placed in public in your region?
Do you already have naked statues in your region?
All questions which could generate interesting responses - whats your take?
