''That is beacause he (and Oda) wants to do it! ''

Indeed. The world in OP is fictionary so everything is just the way the author wants, even though it's impossible in real life. However, if you think about Zoro's will, determination and how much he has trained, it doesn't seem that impossible. After all, we can do many things in real life if we want to and work hard, except for those which are proven impossible by any available means (laws of physics for example).

So I think it's great that Oda managed to make something proven impossible (or so I think it is) seem possible with the help of fiction.
