Small Farm Versus Big Farm

This was brought to my attention:

SWAT Team Conducts Food Raid In Rural Ohio

It raises a lot of questions for me, e.g. ...

Should people who grow food and sell it be required to have a license? How do you determine who gets exempted? Are food co-ops and CSAs (Community Supported Agriculture, pictured) typically exempted from being licensed?

Should people who act as a middle man, buying food from a grower and reselling it, be required to have a license? How do you determine who gets exempted?

I get the feeling this is a growing problem, especially with the increased demand for organic, locally-produced plants and livestock.
