They are running you around the bush, doesn't matter how long you lived there. You could start up today, the MRTFA still applies. Also, in Michigan, I believe you can sell eggs, or "try" i.e. put a sign out in your yard, without a license, as long as you aren't doing it commercially. I am sure they know all this, but are hoping you don't. Keep digging, you are totally in the right here.
