If you think we should have "only wi-fi + cellular" as an option, please report it as a separate bug with use cases. It doesn't affect the resolution of this bug report, and I mentioned it here only because Ondrej repeatedly gave the impression of being confused about what the current options do.

The reason it's obviously wrong isn't that the logic is wrong, it's that the use case isn't realistic. Location use is often long, continuous (e.g. when driving, running, or cycling), and resilient to offline periods; a data transfer hardly ever is.
The one case where I can imagine that analogy working is if there was a BitTorrent client, where you could "start" a download while offline, it paused whenever you went offline, and it started/resumed whenever you were online. In that case, yes, downloading over 4G only *would* usually be slower overall than 2G/3G/4G -- because 2G/3G/4G would be transferring as fast as 4G-only whenever 4G was available, *plus* it would be transferring more of the time. But hardly any apps ever use data like that, and I know of no Ubuntu Touch apps that do. In contrast, most apps that use your location are still useful when you don't have a GPS fix yet, will recalibrate automatically once you do, and don't mind if you lose the fix occasionally. And in those periods when you don't have a fix, GPS only is necessarily less accurate than GPS + cell + wi-fi.
