ELI5: Why can't cellular radio waves be divided for unlimited data carrying?

Since the EM spectrum is analog, couldn't an infinite number of digital channels be created to carry data? 

I'm thinking about these news stories about how the Internet is getting clogged up like a freeway at rush hour with only a few lanes. If we take any given carrier spectrum, why can't it be divided into a near-infinite amount of channels to send data?

The narrower the channel, the less information you can send down it reliably.  Using your freeway example, you could take a 3 lane highway and give yourself 24 bike lanes but nobody'd be getting anywhere very quickly.
