If you can't turn this "feature" off, there's no way I'm wasting time on this game.
I am pretty sure that you can turn that off and also limit it to your friends to join into your game as opposed to random people on the internet, or at least you will probably have an option to allow only friends to join in or everyone from the internet.
Who knows, this is pretty much the very first time they even reveal MP in this game and how it would work so I think it is too early to get all worked up about a feature we know so little of.
I very much doubt that this feature would be something you can not turn off or limit in some ways.
