I'm not saying that all old buildings should be replaced: there are a lot of good examples around, we have many here in Paris too, also thinking of the famous Saarinen TWA Flight Center (still have to see some transformation results on this one though).
However, this one, compared to other projects you mention, won't likely be usable for art or other entertainment as it is located within the airport area. It won't likely work again as an airport facility either, since too small and not adapted to modern requirements. It could maybe become a hotel like the TWA building, but that would likely cost a huge lot of money seeing the current state on the pictures, and the need has to be justified, "tourism" like for the Saarinen building won't probably be enough.
I'd be happy to argue "for" preservation, but the article does not show any viable projects either: it seems like people want to preserve, but without a clear idea about what to do with it.
On the "against" side, there are a lot of new projects replacing old buildings that have been a huge success.
