Something tells me that the NASA scientists involved know a bit more about physics than you, me or Thunderfoot do. I don't think any of us has even a PhD in the subject, never mind practical experience putting things into orbit.
Read the carefully all fine text in the supplied GBR article.
Nasa does not have a clue if it can actually do any work or that any of their personal time or money should be invested in it.
They hope it may be possible to use for sending cargo to space.
They don't know it it can even be made to function at all or even be profitable.
Now, if any PHD in Nasa actually did analyze the device and see it function, wouldn't the article read more like: We at Nasa know this is the future and we will invest our government dollars into making the device and have plans to use it for all our cargo needs which can tolerate the 10000g metric. We reserved prime real estate here in Cape Canaveral for the location of our new Spinlaunch en-devour and plan to ship cargo to orbit in under a decade.
You are looking at a meaningless press release where basically Nasa said they would keep an eye out to see if anything functional ever develops. If it ever does, they might find a use for it. The only 'lucky' possibly manipulative winner move here is Spinlaunch as they got some press with Nasa's name on it. A great credential move.
