The volunteer labor could be applied to domestic infrastructure as in the CCC
Unfortunately the limiting factor on US domestic infrastructure isn’t typically labour but regulatory. Major infrastructure projects have to go through literally years of applications and hearings to get planning permission, with expensive concessions required and no guarantee of success. This occurs both for very small projects - e.g. turning a disused parking lot into a house in the bay area—and large ones—the KeyStone XL pipeline, for example, was originally proposed in 2008… and 12 years later, after exhaustive environmental review, was blocked by the government.
