Wageslave,
Thank your for your very kind words.
Whether Peak Oil occurs in 2010 or 2020, it's just a change in coefficients. The basic equation remains the same and we will be in deep trouble unless we use energy more efficiently and find alternative sources.
Similarly, you don't have to believe in Peak Oil to see that the future is likely to hold a long term imbalance and uncertainty over the supply/demand situation for oil. That's the primary reason I suggested energy investments in "The Coming Generational Storm" (MIT Press, 2004). I see no reason to reduce one's asset allocation to energy in 2008. There is a energy commitment in the Couch Potato Building Block portfolios. And there is an energy commitment in the AssetBuilder portfolios. At AssetBuilder we do it with DBX, the Deutsche Bank Commodities ETF which is about 60 percent energy.
Like you, I don't see any "real hedge against doomsday." I've listened to, and read, the doomsday contingent for decades. All I can say is that I have no interest in being wealthy if I am the Last-Man-Standing. The alternative is to build very diversified portfolios, to keep our obligations low, and to remain capable of adapting. Money doesn't adapt. People adapt and adaptation is our strong suit--- if we will only allow it.
