I think the whole idea is to make that truth a little more...reasonable.
The main post seems to be focused on the 10X system. If the proposal was along the lines of "Players recently attacked cannot be attacked by out players for N hours" then I would agree. But I think that the 10X range is probably the right one for the game to be playable. While there are people out there who do it because they can I think it's more likely that the majority attack because they need the resources. If you restrict the pool, you'll also restrict growth and so ultimately the number of people who can attack you will end up being similar just with higher stakes. If there's a tribe or group who are out there to bully you, you might cause more damage back to them but they will still bully you.
