There's a limited amount of radio spectrum, so it has to be managed. Though technically not unlimited in the strictest sense, internet communications don't have a real limit on how many people can communicate with each other, except limits artificially created.

It's not a technology limitation as you say. The issue is a psychology problem. How do you keep a nation all playing on the same team, so to speak, when there are an infinite number of contradictory voices screaming at them?

My observation is that a society is based on some common ideas, many times myths, but without those common threads you can't make a civilization. This is why dictatorial regimes shut down open internet access rather quickly. They know it will undermine and/or destroy their control of the masses.
