Did anyone realise this about movie trance 2013?

Some spoilers ahead so don't read on if you don't want to spoil the movie.

Did anyone realise that the reason all of the events of the film is all because of the therapist. Elizabeth Lamb? Because if she hadn't hypnotised him into bringing the painting to her then Simon wouldn't have disobeyed Franck therefore not getting hit on the head and not regaining his memory. If this hadn't happened the woman who hit him wouldn't have gotten strangled by Simon and Simon's debt would be cleared. Also the rest of Franck's gang wouldn't have been killed. Also if the stolen painting is just hanging on Elizabeth's wall then if anyone visited her wouldn't they see that's the stolen painting and she gets arrested? Just some things on my mind about the film.
