This is kinda... rude. Like saying that a GUI doesn't serve a purpose when people could read the TTY.

CI gives you areas for your bash scripts to run in self-contained small runs, that may trigger other runs, in a repeatable fashion on a clean environment, on a GUI anybody in your team can see. It gives you quick integrations into things.

CD lets you repeatedly deploy - without forgeting a step that was only known to Phil, the guy that retired three years ago, remembering all the steps and doing something dependably.

Or... you could do bash scripts? https://www.youtube.com/watch?v=40SnEd1RWUU (Just use a VPS, bro)
