The only thing they could steal is things from your personal bazaar. That is not a lot of stuff and all the things in there are stuff you put. Plus if you never go afk then you can keep all the stuff in your bazaar and never get anything stolen. However you get up to get a drink or go to the bathroom and you run the risk of having stuff in your bazaar taken out. It would be like a secondary stealing option so they would have to have the secondary item equipped. This could be a bad idea admittedly but I like it.
