This, like many issues, is a property rights issue. Anyhow, it's already a "right" according to the Maine constitution. What happened is busy bodies eroded that right with zoning and regulation etc.
Section 1. Natural rights. All people are born equally free and independent, and have certain natural, inherent and unalienable rights, among which are those of enjoying and defending life and liberty, acquiring, possessing and protecting property, and of pursuing and obtaining safety and happiness. (From the Maine bill of rights)
Those who favor controlling other people will oppose it and vote to limit a right. These people should be considered food and promptly eviscerated, smoked, then stored and eaten later. Cannibals have rights too!
You have a right to grow your own food on your property or the property of others (with their agreement) trade it, sell it, give it away. You don't have a right to take it from others, without their consent.
People should disobey lawn ordinance horseshit and grow food in their front yards if they're inclined to.
