There’s kind of a two tier function here. One, on somebody’s property and the other being in airspace. Whether you start from somebody’s property and hover over it, or come from someone else’s property and hover over from possibly a point BVLOS to get to the same point via airspace seems immaterial. You wanted to hover or fly over a certain spot regardless of how you got there. In either case you went from property to airspace the second you took off and in reverse when you land.
Now the other problem is if you start from the property of interest and they want to ban that activity “while on their property”, took some effort to arrive at their property to begin with. Besides drone flight, standing, stopping, parking, jaywalking, spitting, walking, running, smoking, fighting, shooting, loitering, driving, bicycling, chewing gum, buying, selling or anything else might also catch the property owners interest which they might also try to ban.
Now in the case of manned aircraft which outside of helicopters that can almost land anywhere it wants to, an airport is required to takeoff and land safely from usually a public airport utilizing quite a bit of real estate. But wherein the pilot is also in the same place as aircraft they are flying, they are usually in some kind of airspace which cannot be construed as trespassing on somebody else’s property, but they do have to avoid incursions with others engaged in the same activity. And they usually have to find a point on the other end that is also suitable to land and take off from.
Arriving at another point from where they started is typically not a feasible option with a drone, as there is a possible undesirable separation between the drone and the operator which may typically be also on somebody else’s property from where they started.
