If it takes 3 days to fold a load of washing, it's still quicker than it takes me now. For commercial use it wouldn't work, but for consumers speed is not an issue.
Mine tends to go from the drier to laying out flat on top of the drier. So the fact it gets folded would be great. Every now and then I actually fold and put away and I feel like an adult. We try not to do that much around here
