I can grant that a typical usage of wireless bandwidth doesn't require more than 10Mbps. So, what does "even faster buy you"?

The answer is actually pretty simple, at any given frequency you have a limited amount of data that can be transmitted. The more people you have chatting to a tower, the less available bandwidth there is. By having a transmission standard with theoretical capacities in the GB or 10GB, or more you make it so you can service 10, 100, 1000 more customers their 10Mbps content. It makes it cheaper for the carrier to roll out and gives a better experience for the end users.
