You've got it backwards -- the very reason that food is plentiful is that there is profit to be made in growing and selling it.

Your statement:

"food isn't scarce for most of us and few have problems acquiring it and the ability to produce it can't be easily collected in the hands of a few, anyone can grow their own food"

is directly contradicted by the millions who starved to death when food production was collectivised under various profit-hating communist regimes.
