I agree in principle that reuse is the best imaginable outcome... but You underestimate the labor and cost of machines. I bet it costs $200 to pluck a single tree let alone ship it somewhere else usable.
It’s actually cheaper just to buy new fruit tree stock and you can get better quality (ie flavorful varieties vs mass farmable ones). Source: worked at an ornamental tree farm, done the math in spreadsheets and have planted peach trees in my yard as well - once loaded a trailer wrong and did a 180 in a loaded flatbed with trees, which went all over the interstate.
