I think another reason involves location, school culture, exposure and history. This is what the true blue bloods have that the aggies lack. If aTm and Texas are offering the same in NIL, how much more would they have to pay for you to go to College Station when you have other options? Most of their problems have nothing to do with money, it has to do with other factors that are attractive to young athletes. Location, prestige, other NIL opportunities, exposure, reputation, winning tradition, and pride. Some people are smart enough to realize that the biggest bag isn't necessarily the best opportunity. Yes, there are players who will chase the biggest bag, but look at how most of those individuals end up. See the 2022 aTm class.
I think some of the boosters are realizing, all things being equal, they just can't win. There was a time when they thought they could throw money at a problem, especially when they had SEC/Jimbo/Johnny Football momentum (and some of the internet fans still think they can), but the fact that they didn't make a leap when they were alone in the SEC, dropping bags, Jimbo, 2022 Class, etc. coupled with our recent success and their lack of it has to have some of their donor base facing reality.
If my son was a 5* athlete the price for him to go to aTm over Texas, Alabama, Fla, Ohio St., Ga., ND, Mich, USC, LSU (just to name a few) would be exponentially higher because of the location, culture and history of the program. That is their real problem and not one anyone on TexAgs will ever see as a factor. "Big bad Texas is outspending us." Their only problem with NIL is that other programs have it too not that they don't have the support for it. Their problems are not fixable because they are their tradition.
