Yeah this is a complex problem. It does seem the case that we probably have enough food globally, but not at a national level. Also it seems that we don't have sufficient food for everyone to live at the level of the average American or European, so arguably there's benefit there in increasing food production. Also a large population still farm every day, being able to reduce the time input for farming could increase productivity by freeing people up to do other things.
