I use to shrug it off, because I said, why can't it then be "this and that" is the necessary being. But when you understand, why something HAS to be, in all possible worlds, then you will see it can't be something in time or has properties that aren't necessary. The reason why it can't be something in time, is because it can always have been in a different time, in a different possible universe. In the case of the necessary being, it is what has to be possibly necessarily so, in all possible worlds.
The reason why it can't be finite, is that it can always be less or more in that existence. Therefore it neccessarily must be something that cannot be increased or decreased. It has to be something that is eternal. It has to be something that doesn't have unneccessary qualities like colours or shape, that can always be different in one possible world over another.
What's weird about it really is that it narrows down the concept to one.
