Quite true on what has been stated, of course a moon mission be beneficial to use some new gear, but as was done in the past, and with private space flight emerging, yet to be verified on its own. The congress will have to set aside funding, so the plan of what was done before with Obama has been reversed, so a lander will have to be planned in the years ahead.
As for Aldrin, he'd be deluding himself to want an outpost on the Moon, Armstrong and Moore are dead, after nearly fifty years when they spoke on the BBC, and Armstrong thought that an outpost would be in their lifetime.
Any sort of outpost on any body in the solar system is going to be expensive, if it isn't decades in the making, it can't work. The interest will fade.
