The point is that you don't want this to just be on LAN, you would want to be able to this from anywhere. That way if you're at work or going out you can still do that. If you wanted it to just be on LAN, you can just disable the cloud features, but for many people that's a big selling point. You can make it work over the internet without a cloud connection, but it's fiddly and requires set-up (port forwarding or hole punching). People don't want that, and Bambu's value proposition is zero-tweaking at high performance - otherwise you'd go for another model.
