Most of the statues represents anonymous people. Since the goal is not to show who they are, but, rather, what they represent. There is a difference between a statue and a bust. A bust, by design, represents someone.
But a statue could be a demonstration of the ideas that Satoshi represented. Still, it would be a personal view of the artist on Nakamoto. But in that case, a face would not be the most important, but all the dress and attitude of the statue.
I've seen very few statues represent anonymous people. Most have a recognizable face, bust or statue. But I do like your image. I still think the idea is ridiculous. If Satoshi wanted a statue in his honor, he would have come out and taken credit for revolutionizing payments and currencies. The man has single-handedly begun a financial revolution of magnum proportions. The world is moving digital and quickly.
He decided to remain anonymous for his own good yet he do know the possible things do might happen when he would tend to get out and shown himself into the public. There would be lots of questions and possible problems of hunting him down due to his creation and now we arent still able to know on whos satoshi nakamoto but yet people do recognize on the project he did made which really do make a change when it comes to payment system. Any statue or monument would do as long it signifies it anonymity it would be considerable.
