Economic MOL seems like it makes sense. Part of the problem is systemic risk. At some point, one starts losing the electric supply, perhaps because of indirect impacts (financial (?)). Once the electric system start to go, everything else is much more difficult. Of course there is the pipeline issue as well, and the amount of overhead of the super majors.

I think the MOL is more for corporate business/globalisation. Eg at some point cellphones will [thankfully] become uneconomic. So far I have managed to avoid them and I'm still here.

This guy's apprentice will still make you a Samuria sword out of a few bags of iron sand a long time after that:
