attachment to emptiness

  I think one of the most important elements of Lotus Sutra that interests me is this idea that attachment to the 'concept' or the incorrect view of emptiness can be harmful to one's practice and to one's being in general. Buddha is even suggesting, in some regards, that it is harder for a person to be saved from attaching to emptiness than it is to save them from attachment to existence. I wonder what are the implications of this view, and how does it allow a person to be socially engaged? I am really asking the question: how does a person move from attachment to emptiness (or at least a false, distorted view of it) to real engagement in the world? And how is this achieved without 'reattaching' to existence?
    I think the answer to this is to recognize that the six sense objects are neither bad nor desirable. They are not to be avoided altogether, since it is through the whole mind that people can reach enlightenment (eg. by way of practice). But at the same time, I do begin to wonder how it's possible for a person to truly live and be human if one falls into the nihilistic trap of seeing all things as coming and going --by nature, full of impermanence. More importantly, how is it that people can muster enthusiasm for things  which are fundamentally impermanent?
    The point is that avoidance of existence becomes an obstruction because that concept of emptiness becomes a kind of craving for 'non being'. But if a person truly realizes that she or he is never detached from the world (or that world and mind are one), there is no such confusion that  says that all things are to be escaped or avoided because they are impermanent. In fact, nothing is really to be feared anymore, since it is all happening in the realm of phenomena. In this way, even socializing can be a way of practicing not attaching to views or to particular preferences.
    I  think the mistake that perhaps those who attach to emptiness make is that they are attaching to a partial view--the view that emptiness is a 'relief' from existence. Such isn't the case, since emptiness and existence go  together and are inseparable from each other. To see emptiness in existence is to know that there is no need to escape from this moment. It is part of us and not something that needs to be avoided. It's like the hand and foot: why would I want to cut these off from my body, unless I had the deluded view that I am separate from them? When I relax in this moment, I am no longer trying to resist painful sensations, and I can be clear about the totality of the experience as inseparable from mind itself.
