IAnd saying "things only happen BECAUSE they are, or will be, seen" seems pretty anthopocentric to me, unless you give a much more rigorous definition of 'things'. As for the idea that "the media gaze instigates pseudo-events, 'happenings' which would never take place unless they were filmed or reported" - well, sure, people have always played up to the camera, this isn't new. Neither is it universally true - I hardly thing the Congolese have spent the past ten years butchering each other for the benefit of the developed world's media gaze, especially given the scandalously small amount of attention being paid to the conflict.
It becomes clear that you are not familiar with Lacanian psychoanalysis here. Baudrillard's metaphysics are very firmly rooted in the psychoanalytical tradition. You would really have to read up on Lacan's use of "the Real" to even have a clue where Baudrillard is coming from (apparently.)
