Conceivably true? We could be in a world with no DRM, but there would still be a market trend moving games towards a more social, connected and integrated experience; and some developers will be looking at ways to fundamentally build their new games in a way that takes advantage of this. Why not SimCity? The Sims 3 already indicated where the Sims franchise might be heading with regards to improved connectivity with friends, I don't think it's an entirely unreasonable leap to get to where SimCity is now.
Which isn't to say that DRM wouldn't have been a business consideration at an executive level; but there's definitely an argument that SimCity's design choices, even if flawed, can be justified without considering DRM.
