Both of these statements race to the same question: Are we as a country going to be better off if we allow the same few companies to monopolize those frequencies that are available or if we keep the same monopoly rules in place and allow radio broadcasting to ultimately fail, if that is where this is headed. If this is the choice we now face, then I would vote for the latter alternative. Why? Because (as @davideduardo has theorized given his Latin American background and experience), if all radio frequencies become only the home of national networks owned by either one or a small handful of companies, then if things turn around, there would be absolutely no room for newer and smaller players to enter the fray.
I'll give you that your position is consistent and attempts to acknowledge reality in ways that those who want to return to 7-7-7 don't.
Allow me, however, to point out a major flaw. In the event "things turn around," what makes you think newer and smaller players will be the ones to enter the fray? History, and even the present, don't suggest that will happen. Connoisseur, for example, is not a new player. It has been around since the mid-to-late 90's and was slowly getting back into the business and building an empire after selling its stations to Cumulus around 25 years ago. It's now one of the four biggest operators and is not seemingly content with being a bit player where it operates. Most every market also lacks at least one of the big five broadcasting companies. If radio does turn around, do you think those companies won't want to expand where they're not presently operating? They almost certainly will.
Even if new players enter, enticed by an increasing stream of revenue, they're unlikely to be content remaining small. If the past is any indication, the smaller operators currently buying stations, like the company buying Connoisseur's Bakersfield stations, will be the first to cash out. When the Telecommunications Act of 1996 passed, we didn't see mom and pop operators go on nationwide buying sprees and building large clusters.
I don't like the idea of network radio much more than you do, and I'm not big on allowing a second major wave of consolidation either. I'd rather any such wave be managed slowly and gradually. The idea, however, that radio will somehow become a haven for new and innovative small businesses is rooted in Fantasyland.
