It isn't, and no nationalist here brought up oil first co-incidently but if you aren't looking for such nuances you'll walk right past it...
Independence is not just about oil revenues, although that is clearly a proportion of the case.
See what you said about the oil fields - that myth has been regurgitated decade on decade for 40 years.
Oil will last for another 40 years at least, and iirc the oldest oil well in the world is still producing oil albeit in a now reduced fashion. 100+ years.
It is a myth that production has declined massivelly from its high point in 99? Have you some alternative production figures?
I'm not anti-independence though
