By their own stated beliefs, this commodity's price will be orders of magnitude higher in the future. Thus, if their beliefs are correct, they can make a killing. Scratch that: they're guaranteed to make a killing.
The added benefit is that if people would just do this - put their money where their mouth is - would drive up the price of oil today, reducing consumption (a little), and staving off the disaster (a little) that these people claim to believe is coming. Further, the higher price of oil today would bring energy alternatives closer to the point of being economical. The price of oil would be incorporating this idea that some disastrous "peak oil" is coming, and this price signal would tell the market to develop alternatives - which it would. I mean heck, that's how the market is supposed to work!
So there's really no excuse for these people to be spending so much effort jibber-jabbering about "peak oil" if they are not investing in oil.
