Because they want to learn how to write all that code. Or, they have an
idea for a game that does not fit any game engine they have found. Or,
they are writing for a special platform that will not support a full
blown game engine. Or, they may even think they can do better and want
to see if they can. Or, just possibly they looked at a bunch of game
engines and realized that they might get done faster by doing it in C++
than taking the time to learn a game engine.

Many reasons exist. You might as well ask why someone would climb a
mountain rather than just fly over it and take a picture. I can tell
you, the experience is not the same.
