I respect your abilities in Portraiture, although you have never posted a single photo.
Having shot 100's of Moon shots I'll tell you outright you are wrong on both counts.
The VR freezes the frame for a short period of time whether the Camera is on a tripod or rolling down a hill.
And the Moon in a telephoto lens is moving fast.

...and from The Nikon D3300 Reference Manual Technical Notes, Page 355:
"...VR II lenses support vibration reduction (VR), which reduces blur caused by camera shake, allowing shutter speeds up to 4.0 stops slower than would otherwise be the case (measured at [maximum focal length] with a DX-format camera according to Camera and Imaging Products Association [CIPA] standards; effects vary with the photographer and shooting conditions). This increases the range of shutter speeds available and permits hand-held, tripod-free photography in a wide range of situations.
To use vibration reduction, slide the vibration reduction switch to ON. Vibration reduction is activated when the shutter-release button is pressed halfway, reducing the effects of camera shake on the image in the viewfinder and simplifying the process of framing the subject and focusing in both autofocus and manual focus modes. When the camera is panned, vibration reduction applies only to motion that is not part of the pan (if the camera is panned horizontally, for example, vibration reduction will be applied only to vertical shake), making it much easier to pan the camera smoothly in a wide arc.
Turn vibration reduction off when the camera is securely mounted on a tripod, but leave it on if the tripod head is not secured or when using a monopod."
My own tests with a 24-120mm VR lens (and other VR/IS/VC lenses from various manufacturers) bear this out. There is simply no action-stopping benefit to VR/IS/IBIS/VC technologies, whether in-lens or in-body. There is a very real and useful *camera motion* blur-stopping benefit for hand-held photography and photography on a monopod or loose gimbal headed tripod. The latest lenses let you go three or four stops slower on the shutter speed dial. Older VR type lenses only gain about two or three stops' benefit.

Craig, I've been burned a few times, and found my images used on sites I did not post them to, and in one case, used as a background in an ad! Never again. I simply don't post images on the Internet for which I'm interested in retaining the copyrights and reproduction revenues. I cannot post any images from my career at Delmar, Herff Jones Photography Division, or Lifetouch, because they are all now the property of Lifetouch.
I'm working on a blog site, which at some point will become a showcase for my own Q&A training materials. Until it's released, I don't post at all.
My primary experience in photography has been in yearbook photojournalism, nature photography, photo illustration of products, processes, and machinery, and corporate PR and training work not portraiture. I taught portraiture, after developing training materials from the advice and input of many subject matter experts, but it's not my passion (despite 33 years in the business!).
I was the "photo consultant of last resort" at Delmar and Herff Jones Photography. I would take the customer calls no one else in that Charlotte lab could answer. I would research the issue, make tests, and do whatever it took to repeat a problem, find a solution, and explain it to the curious client. (I had a large studio, where I tested and documented Canon, Nikon, and pro lighting gear for training.)
It was a customer complaint about lack of sharpness that led me to test this VR stuff on my own. He was making available light senior portraits, on a secure, heavy-duty Bogen tripod, at 1/30 second, with VR turned on. His images were sometimes fuzzy, sometimes sharp. Once I figured out he needed to turn off VR when on a tripod, his problems disappeared. Once he figured out he could shoot at 1/60 all day long with VR on, and NO tripod, he was happy.
