I don't know about that. The Eiffel Tower, The St. Louis Arch, The Space Needle, and many similar structures were really just built as center pieces for fairs. In fact, there's really less meaning to those than there would be for this in concept, however they have become more iconic than this probably ever would be.

If you meant to say that, because it's concept has meaning, then it has less chance of being iconic, then you may have a point, as many "icons" were conceived and built for nothing more than their iconic potential, as were the ones I listed above. And it seems a lot of the criticism here is more about aesthetic than meaning. It seems people would be open to the idea more if it didn't look or represent anything (specifically, an oil derrick), but would rather that it just look cool.
