Limitless freedom: are you really free?

I've been thinking about the concept of enlightenment, in terms of attaining a state of non-attachment to everything as well as what the result might look like and I think it might be something like experiencing limitless freedom.You become everything and nothing, but because there are no limitations you can never turn that possibility into something real. In fact, you the person don't even exist. A rather tenuous existence, and while a person might be one with everything and nothing, what in the end does that really mean, and what does it really do for the person. I'll admit I'm attached to my identity.
