It's many, many, many orders of magnitude difference.

I haven't done the math but my hunch is you could fit the entire ham allocation from VHF down in a single 10mbit pipe. VHF is usually 1200bps per channel and gets slower as you get lower in bandwidth.

Okay but you're still ignoring the main question "how does encryption require more bandwidth?"
