As I understand it, most of the gas that would be delivered via NS2 would be the gas that wouldn't be delivered through Belarus/Ukraine (depriving them of transit revenue and providing more options for Russia to employ gas politics on its western flank). It rather seems to me that, far from being natural in a world without geopolitical drama, much of its purpose is actually to enable geopolitical drama.
And, of course, the main thrust of the argumentation against NS2 was that it was causing Germany to pursue an economic dependency on Russia that was unwise, given Russia's already-demonstrated penchant for using that economic dependency as a lever in global affairs. NS2 died when Russia's invasion of Ukraine demonstrated the lack of wisdom in pursuing economic dependency on Russia (compounded by Russia withholding gas flows to make Europe came back begging to Mother Russia).
