I would imagine that for most people, putting away is the annoying and effortful step of the cleaning process. I wouldn't really count gathering dirty dishes as a step that's specific to having a machine since without a machine since they'd need to be gathered to be cleaned anyway. Once dishes are gathered, loading the dishwasher is easy because the dishes are already as close to the dishwasher as physically possible in most kitchen layouts, the specific organization of the dishes in the washer is generally more flexible than how they are organized in the cabinets, and gravity assists you while loading while it works against you while putting away.

The same benefit as anything else that's automated - not having to deal with humans. A machine where you could dump dirty laundry in any time and have it pop out neat and folded would be far superior than having to work with a third-party schedule and live human beings, just like an ATM is far superior to a bank teller 99% of the time if you need cash at a specific time and location.
2. You still have to arrange time to meet them or drive there, putting your clothes together and then taking them back
for 2, I don't know about the US but in the UK you can get small local companies that will wash and iron a sack of laundry for you, and return them folded. I don't know what benefit you would see by having that automated instead of done by a human. It's fairly cheap too I understand.
