PVP integration into the game. How do you feel about it?

I would really want to have pvp. You know building your bases then raid other ones, making traps ... It would be totally awesome to have such feature. But as of right now the most pvp you can have is just putting the settings of player damage to on and structures to on and basically it's done. But then the problem rises that there might be people who will turn it off and ruin the entire server. But maybe the developers could add a button to make damage on for the entire server not minding the settings. How do you think of this idea?
