Doomers - idea being to lay out an area for those with the worst case scenario ideas to put it out. Many of the end of society philosophy see permaculture as having some ideologically compatible tenets, in regards to self sufficiency. Would be interesting to give these people a place to voice their ideas, even it does involve guns and eating cockroaches
Endgame - philosophical questions, the basics behind "permanent culture", and not the whole problem that humanity has suffered with over the last 2000 years, mainly the growth and conflict of differing ideologies. If we are to have differing basic philosophies, how do we keep humanities goals in check with the realities of what is sustainable. Democracy has been found out to be the ideal political system of free market economics as it gives you the ability to buy power. I think that the older ethos of "elder" should be something that is a better foundation for society. But that's me. I do figure that permaculture, as being a meme that pulls in ideas from so many different cultures and belief systems, is a great overall boundary in which to study these things, the same way as we study "guilds" of plants and systems.
Anyway, I know that a lot of people have become scared of these overall topics (with reason) but I still think it is something that needs to be talked about. Acceptance of the norm is...blah.
