As it is a reality show, the people will have been chosen mainly for that reason.
It would be nice to see more survival and less squabbles, but I doubt that the show has been set up like that.
And if there was not enough squabbles, I suspect the programme makers would inject it in some way. And/or cut the programme short.
I could be wrong.
I am not sure how I would cope in the no conveniences situation. Not as bad as some I think, but I would probably crack part way through and walk back to civilisation.
But if it is anything like shows like Big Brother, I think people forfeit their fee, or some of it, if they walk, so that would stop or delay them doing that.
We shall see. I think the programme is quite watchable at the moment.
