I believe the issue with human waste for fertilizer has to do with the fact that we eat meat. Same reason you don't want to use dog or cat waste in your garden.
Getting off toxic Monsanto food products won't change this fact. The only way to fix this would be to have everyone in the community become a vegetarian, and I sure as hell wouldn't want to live there if I'm not free to eat a steak.
peace + liberty = prosperity
