D&D 5E - Want a better Rogue? Build a Wizard. Or why play a Rogue?

The title describes a conversation I recently had with a player. He likes to build characters of all types - not necessarily a min/maxer, but tries to embrace what a class is good at it. He could not come up with a fun build for a rogue. Almost everything a rogue does - the wizard does better. Knock, Invisibility, and other spells are effectively better than the rogue's skills. To make matters worse, the thing the rogue does semi-decently is to move ahead of the party and scout the situation - in other words, the best use of a rogue is fun for exactly one player at the table.

I am pretty much a DM exclusively, but I could not disagree with the player's point of view.

If you value the enjoyment of the game by the group as a whole - why ever play a rogue? What can a rogue do better than anyone else?

BTW - with the last name of Pogue, I am particularly sensitive to folks labeling the class FKA thief as some sort of make-up
