You are logged in as a different user (probably root) than the owner of 
the display ":0.0". Only the owner of the display can grant access to it. 
E.g. if you log in as bill and then start Konsole and enter the command 
sudo su to have a root shell you can't start the xhost command you 
mentioned above. And you shouldn't use / need it anyway because it is 
dangerous if your machine is accessible via network.  Use kdesu instead 
to start a command with access to your display.
