Why would somebody use "select" for this at all? I.e., if you were going to write:

  select {
    case send/receive statement:
      statement
      ...
  }

Why not just write:

  send/receive statement
  statement
  ...

What am I missing?

I believe the GP was referring to select-with-one-case-and-a-default, like

  select {
    case <- ch:
    default:
  }

Channel send/recv is a blocking operation, select is a commonly used workaround to make it non-blocking.
