Here's a thought: as long as some countries somewhere have enough freedom to innovate, and entrepreneurs can leave their countries and get to the freer ones, countries like Norway can piggyback off all the innovation from others (or outsource it). I think it would only be a problem if for some reason there was technology that couldn't be copied.

How will they pay for that technology they need to import when the oil ends? They'd need to barter something for something else.
