That's why the ontological framing is important- notice that 'powerful' doesn't mean anything inherently. Being, on the other hand, is necessary and inescapable for any metaphysical framework. To have anything, being must exist, necessarily. Therefore, to imagine the greatest possible being, seems not so much a stretch, compared to an arbitrary characteristic, such as 'power'. That there is a must 'powerful universe' does not seem a priori necessary, whereas insofar as existance exists, there is necessarily a greatest possible being. That is not to say that you can get to any meaningful conception of a God from that ontological framework, only that the it is only an argument when it is framed ontologically- once you stretch it to other domains, the inherent strength of the argument fails.
