Why can you not download Gunz Online on Gunzonline?

You can't download the game GunZ anymore on GunZonline because that was the international GunZ, also known as IGUNZ. Try using www.ijji.com to download GunZ.

And because the people that make it cant be bothered to put the download button on their website!

The international GunZ was stopped and rumors say the creators of GunZ:The Duel sold the rights of the game to ijji(but that is not much believed).
