HaHa, really funny writing. Opootunity, LoL!
My husband and I looked into permaculture years ago, but never managed to move from the city to the country. I once read somewhere that in the old days (somewhere in Asia?), the owners of a house were severely offended if their dinner guests didn't leave a "gift" behind too. :D

I'm familiar with the fact that human poo can be used as compost and I grew up with an outhouse as a little girl. I also learnt that it's best not to mix Pippi with Poppo. How to solve this problem in cities, however, is still something I don't know.
You can tell how much you enjoy the topic and also the prospect that your own property can be perma-managed in this way.
I find it refreshing that you don't proselytise.
Greetings!
