Also think of angles. At 100m your drone is looking down, in basically the same direction as a satellite. But during those few seconds when you takeoff/land your camera is probably pointing sideways, a perspective that a satellite cannot replicate. Rather than simply a higher resolution, those few seconds at low altitudes give a very different perspective on an object. If you want to see the underside of a bridge, to determine if its support can handle tanks, you won't get that information looking down from 100m. You will get it looking sideways from 2m.
