There really are two cases where a throttle comes in handy:
To a lesser extent the throttle can help you start on hills. I can see that although I always peddle to start the bike while holding the motor cut-out button (Large Green Button) and then let the PAS engage then feather on the throttle if necessary... but yes it can help if you are willing to sacrifice the power to start the mass moving with the motor.
When you are maneuvering the bike at very low speeds or in a tight spot where the pedals could give you too much momentum. Agreed. Another point is in snow when a smooth steady power without pumping your legs helps to keep a smooth straight line on uber slippery surfaces.
I don't consider the "broken chain" hypothetical a serious one. Chain breaks are exceedingly rare and any number of other more plausible mechanical failures might leave your bike inoperable, hub drive or not. For that matter, it is much easier to fix a flat on a mid-drive bike (largely because you don't need to disconnect the power to the motor, but also because the wheel is much lighter and much easier to pick up and work on without a hub drive in it) -- yet that is rarely mentioned as a disadvantage of hub drives. I carry an extra chain and links so I don't worry about the durability of the chain just the level of wear and that it's well lubricated. I agree that hub-motors make it more difficult to remove the wheel, hell some fat-tire riders repair their flats with the wheel still on the bike rather than taking it off. But the biggest difference is that the weight of the motor isn't suspended with hub-motors and they take an unnecessary beating. I guess it doesn't matter much when and if you specifically buy a bike that's low-rent and considered disposable. "It only costs $999.00 so..." My Rohloff costs more than many low-rent complete production ebikes and there a reason for that.
