Take away what some people use to defend themselves to travel the dangerous wasteland, as well as to and from Vegas? Sound like a bunch of thieves and highwaymen to me. Bad for business too. Can't support them either way. Worse, because both House and Yes-Man require some highly advanced robots to bring law and order around the place (robots with auto-repair systems, missiles, grenades, and LASERS) that they may deem as "forbidden,", there's a pretty good reason these guys aren't something you can outright ignore, let alone tolerate. Hell, they haven't changed their pre-NCR war ways at all, what's to suggest they won't eventually decide to war against Vegas for the same reason they warred with the NCR?
Besides, if you don't think people can be trusted, then why should we place our trust in those big bad energy weapons to the Brotherhood? What makes them better than everyone else? Why are they worthy of them? Why should people have to abide by their rules?
