It’s super easy to grow, decriminalized in a number of US areas already, and I highly suggest you look into it. Uncle Ben’s shelf stable precooked rice is a great, nearly-foolproof way to give it a go (~$1/bag = ¼lb of mushrooms or more).

I appreciate your thought-out response, truly. You make a number of valid points, and have inspired me to look a bit further into the details of our government’s current state of wholly fucked.
