Infinite re-roll for me is synonymous with Story mode difficulty. I think it's totally OK. Normally I am hard-core no-reload gamer but I can imagine myself in mood for this type of re-roll playthrough. Even now, in EA, I am save-scumming often from sheer curiosity and my testing fetish. Both playstyles are legit. Sometime you may want a concrete story, sometimes you may want random turmoil.
