Why would a monopoly be interested in providing the near possible service? They can simply lobby to make upstarts impossible, or buy them, or bleed them dry with localised dumping prices, or steal all of their best ideas given they have more resources. All of these have much higher margins. It's not a "weird thing" it's the inherent reason why anti trust laws and regulations are required for efficient markets, and why rent seekers always argue for free markets
