Your point is well taken.  However, look at it this way.....

if a guy has enough ambition to learn all those skills,  and he can't find land to farm, do you think he is going to stop and say "well, I can't find land, so I won't be able to farm."  ???  Not likely.  A guy (or gal) with that kind of ambition is going to start their own business, whatever it may be - a custom farming business, agri-business, etc, etc, etc 

A person like that is going to be thinking outside the box.
