A very good point, I was also concerned about that. You'd have to be careful drafting the amendment, and make sure of how the state constitution's preamble is worded, to make sure that you're recognizing rights, not granting them. I've seen (in general), various US congress bills in the process of being drafted on other issues, for purposes of clarifying/reclaiming rights that have been taken away (seemingly) by administrative procedures, though I don't think anyone knows how all that'll play out.The US Constitution allows that “life, liberty, and the pursuit of happiness” are unalienable rights. I believe that covers obtaining food, shelter, and clothing for oneself, within the requirements of the local community. If local government bodies put restrictions on gardens or animals used for food, the place to change it is at that lowest government level, not in such a far reaching and imprecise amendment to a state constitution.
