That is an extremely short-sighted viewpoint. Money isn't everything. First of all, if all you care about it direct funding from it, they would easily be able to monetize this by reselling it at auction. Putting it in a museum would enrich people's lives, which is invaluable. Having displays with things like this, are ways people get inspired to do what they can to help in space exploration, either through their own talents or with donations. These "antiques" could very well inspire the next generation of space explorers, which are kind of necessary because the ones we have now are expected to die at some point.
