Obviously the specific issues with Stapleton went beyond its acreage, and I don't know them all. But it seems possible that it could have gotten to the current traffic levels with upgrades rather than a replacement. My guess is it would have needed to relocate the N-S runways to space them out much further, which would have involved imminent domain. And of course it would have needed reconfigured/added terminals. All of that might have cost as much as DIA, with a lot of challenges. And Sea-Tac might always have noise issues. But Stapleton would have meant less sprawl.

It seems implausible that Stapleton would have been able to process 60+ million passengers a year, much less 80 million by 2025, which is DIA's goal. The runway layout was inefficient, and it was much less reliable in winter weather operations. The concourses were small, and there wasn't much room to build more. There was a lot of opposition to expanding an airport on one of the most polluted nuclear superfund sites in the country, and a lot of neighbors wanted to see the airport go. Using eminent domain around Stapleton would have been politically unpopular.
It would have really taken a lot of effort to get Stapleton up to contemporary standards. Even then, it probably would have maxed out at some point and we'd be talking about building a secondary reliever airport somewhere else, which would have also contributed to more sprawl.
It's also worth pointing out that Stapleton did turn into a nice redevelopment opportunity as a close-in neighborhood. It probably could have been denser, and I'm sure the Stapleton neighborhood would be denser if we were building it today, but it wasn't a bad result given that much of it was planned in the late 80s.
