That doesn't make sense. Oblivion in 2006 had instanced cities, but it certainly didn't have as many NPCs in, say, the Imperial City as Vivec in Morrowind did--and Vivec was entirely non-instanced, you could walk anywhere in it without a loading transition. Whatever reason they chose to introduce instanced cities was, it wasn't because of the number of NPCs.
