Such as local telephone companies would enter by way of the resale provisions, or entrance through the use of unbundled network elements, or building their own infrastructure and then connecting that infrastructure to existing networks. A possible outcome of this scenario would be outcome would have been a world where, after massive and diverse entry, the market would stabilize as a market without resale, and without unbundling, but just with facilities-based competition. Resale and unbundling on this view would have been understood as options designed to assist new entrants, and the lesson of the 1996 Act would have been that those crunches were not necessary over time as competition took hold. Suppose instead that entrant continued to use resale and unbundling even after two decades. How would a world where resale and unbundling had turned out to be popular and long-lasting. What exactly would those facts teach us about the 1996 Act and/or local telephone competition
