I think it is amazing that a sovereign state has taken interest in making such a lavish offering to the Buddha. The idea of making such a lavish offering is debatable whether if such an offering is even necessary. I think that such offerings can be 'downsized' and much of the money can really be channeled to real charitable causes. It does make sense to make such lavished offerings to the 3 Jewels when there's just so many charitable causes that deserve some donation and attention. That in itself is not in the spirit of the Mahayana. However, this does not take away from the importance of making offerings to the 3 Jewel.
