I seem to recall our VFW wanting new rifles and not being able to get them. This was all about 20 years ago and they had a dozen Krags they wanted to get rid of. I think part of the problem was no one knowing exactly what to do to get them and they did eventually get them upgraded to 03's. They were for a time under the impression they could sell them and buy new ones. So it isn't to be unexpected that these organizations don't think they actually own the rifles. They've possessed them for many decades and those that acquired them are probably long gone.
I see nothing shameful in the government trying to get back what it owns, especially when they are replacing them with newer models. Isn't really a money making venture, they could probably get more for the garands considering the bore conditions most of these ceremonial rifles are in.
Bottom line is people don't like change much, yet change happens whether you like it or not.
