Most doctile snakes? I think not.

Go to the big open africa and try to find a tame Ball

I don't think that has to do with the amount of space. More likely it's because a ball python living in Africa has never seen a human and is certainly not handled everyday by one, that and they have to deal with parasites and predators.

I would have to agree with wuldier and aSnakeLovinBabe, a large enclosure can work but it takes a lot more effort to provide a suitable environment. I would think that most people that keep their BPs in huge tanks do not properly provide a suitable environment. It's more simple to tell someone to switch their snake to a tub or a smaller tank than to give them instructions on how to make a 100g tank work.
