Earlier quoted context omitted.
"exporting your own oil and gas to be able to have a 'clean' (and up to recently heavily subsidized) transportation network is in a way just a gigantic bookkeeping trick" How so? If every oil exporter used some of their oil revenue to switch to EVs, that would, all things equal, hasten the transition to EVs. The U.S. is not doing that.
"If every oil exporter used some of their oil revenue to switch to EVs, that would, all things equal, hasten the transition to EVs." The premise is all things aren't equal. The oil Norway would have used just gets used somewhere else so what difference does it make what Norway does instead. I don't know if that's the reality of the situation but if it is just an offset, it does sound like a bookkeeping trick doesn't…
Norway exporting oil increases oil supply, but doesn't increase consumption. The world's oil consumers are not supply-constrained; the producers are not running at 100% capacity, and they'll happily pick up the slack if Norway just stopped exporting oil for no reason. And there's a large amount of consumption that can't be offset by electrification in the first place (petrochemicals, long distance flight, etc) so there's not even a theoretical future end-state where they require a non-EV-using counterparty to buy their oil to fund their EV usage.
Calling it a "bookkeeping trick" is just verbal sleigh-of-hand.
