It's astounding that this author believes size alone is evidence of competitiveness. It completely ignores the ample evidence that very large firms achieve market and regulatory capture in a way that biases them towards anti-competitive behavior by establishing barriers to entry. They maximize revenue by denying their customers access to competitors. There is no simple continuum. The sparse examples he mentions do not offer evidence of causal relationships. But it also misses the biggest point: regulation needs to promote competitiveness. Size of firms isn't particularly significant if you get that right.
