He doesn't have a "right" to dictate what a person does. However, given that there are a finite amount of GA aircraft, and I bet more piston AC rot away every year than come off the assembly line, it would be better for everyone if people did not let planes rot to a point they'll never fly again.
On the other side of the market, is there any reason to believe that there are buyers waiting for these airplanes? At the current time there are 143 M series Mooneys of various ages listed on Trade-a-Plane, would adding more to the for sale side of the market make any difference? As long as the pilot population continues to decline, I'd expect the fleet to decrease as well.
