If I may..
If you have to base this argument on anything it should probably be this -- Mihawk kept wondering if it was fate intervening to stop him from killing Luffy. He kept throwing death blows. But, time and time again someone or something would get in his way.
Examples of that include Buggy being in the area because of Luffy bringing him there from Impel Down. It was Luffy's strong spirit, which brings people together, that allowed him to escape his grasp.
It's no cheap illusion or trick.
