i suppose you are correct for the vast majority of growers in your state.
all i can come back with is that i voted for a ballot measure in nov 2010 that would have taken 10% out of whatever i made in addition to all normal taxes, plus a $1,000 per year fee to be a legal 'producer'. of course, like all ballot measures concerning cannabis (except 203 in AZ) it got voted down by an outpouring of tea partiers at the polls.
the people in my state spoke loud and clearly: NO, WE DON'T WANT YOUR MONEY.
that's good enough for me for now, but we'll be back at the polls in 2012 to try to get them to take our money so that we may come out of the cannabis closet.
