The selling point might be to finally have an "automatic" bike. Standard derailleurs are basically like having a stick shift on a car. The rider has to be trained on how to use them and they will make errors like leaving the gear setting too high when going on an uphill and then being unable to downshift because they aren't turning the pedals fast enough due to the high gear ratio.
This is literally just get on and start pedaling and the bike figures out the rest. It even makes e-bike controls super easy, since you can just set a speed and start pedaling and it will supply just enough juice to make up the difference.
The obvious downside is that it's going to be less efficient than a chain drive, because nothing beats a chain drive. But if you basically get the benefits of an e-bike for free then the efficiency loss isn't a big deal for the rider.
