The problem is every aircraft model flies differently. The remote pilot would need to be familiar with that particular type of aircraft to safely land it.
I'm thinking of higher-level contributions such looking at the weather and saying 'fly to this airport and use this runway'; or asking the passenger, 'what does this gauge say?' or 'look at the left engine; what do you see?'; or talking to air traffic control.
One major difference is if a uav crashes no one dies. But in china there is apparently now a commercial pilotless flying ev taxi service - which is autonomous with a human on the ground in the loop as you are suggesting.
Remote piloting for landing an aircraft that size is problematic because you need more sensors on the aircraft plus a reliable, high-bandwidth, low-latency data link. That doesn't really exist in most places. When the military lands something like an MQ-9 Reaper they typically hand off control to a pilot located within line-of-sight right at the airfield. That obviously isn't practical for civilian general aviation.
