I disagree. This is exactly what happened with the initial launch of Healthcare.gov after the Affordable Care Act. The government spent hundreds of millions contracting a large firm that completely botched the site, it couldn't even handle a few hundred users at launch.

Then a small team of highly skilled engineers from Google/Facebook etc were brought in to fix it. They stabilized and relaunched the system in weeks at a fraction of the original cost. It showed that the problem wasn't the complexity or the standards, it was how the project was managed and who was building it.
