I think you're engaging in a logical fallacy. Using a "GUI" isn't "one true way" as there are a near infinite amount of ways to structure a GUI. Command line tools often use graphics to display their results and GUI tools often show their results in textual form so the main difference between a command line interface and a GUI interface is how to provide input. With a GUI I have to click in the right place to make actions happen. This puts more onus on the developer to make sure everything is where it is expected. With a command line tool I have to read a document or help output about how to use it and memorize this information if I wish to be efficient. I'm not saying there should be no command line. It's simply my view that the command line should be treated like XML: not for human consumption. I think this would also potentially make command line tools even better at providing an interface for scripting tools if this was the only expectation placed on them.
