To me, the point is you don't need many flags for ls to be useful. You will learn a few idioms early, such as ls -a and ls -lR but after that, the rest of the flags are nice to haves: if you wish there was a certain feature, you can look it up on the man pages etc. "I wish I could sort by time - oh there's -t"
