It's too easy to point out the self-evident lie here: It's impossible to be "in control" of the Warp. Not even the Emperor was able to control it to such an extent that he was able to foresee the exact circumstances of his demise, let alone the betrayal staged against him, and so it's a false notion starting from the very top.
Being able to light your sword on fire and twirl wraithbone around does not mean you dominate the Warp. In fact, wouldn't it mean the opposite? You become dependent upon that which is feeding off of you? Think of any limited resource used for fuel, like fossil fuels: You tap them, you build up massive civilizations... and it runs out. You were not its master; it had mastery over you, and the moment it is no longer available or under a semblance of "control" you are all but destroyed by it.
Consider that the Emperor was probably relying on his psychic powers to divine the future, rather than speaking to and listening to his people/sons. We know how that ended.
The Eldar used their psychic powers to increase the power of their indulgences. We know how that ended, too.
Humans have had a chance to sit back and watch this occur. Why would it follow in these footsteps? Unless polypsykana can come up with 'damn' good reasons as to how it can truly be reined in, then I don't buy it. It makes no sense to do so.
