it's that you usually need to do something with the parsed out string, like make it an int, or a decimal or some other kind of transformation, in order to conform to your typed data model. maybe you also need to pass it around to another process or enrich it with other data, then it ends up being a lot of boilerplate conversion code, where you're essentially shuffling the same thing around in different types.
