Obviously it very much depends on the 100 lines of code if that was a creative act or not:

    var x = 0
    x = 0
    x = 0
    x = 0
    x = 0
    x = 0
    x = 0
    x = 0
    x = 0
    x = 0
    x = 0
    x = 0
    x = 0
    x = 0
    x = 0
    x = 0
    x = 0
    x = 0
    x = 0
    x = 0
    x = 0
    x = 0
    x = 0
    x = 0
    x = 0
    x = 0
    x = 0
    x = 0
    x = 0
    x = 0
    x = 0
    x = 0
    x = 0

    x = 0
    x = 0

is this supposed to be sarcasm? in case its not: just because you've created something that didnt exist before doesn't define you as creative. quality and ingenuity also matter

Quality and ingenuity are subjective.

also maybe some creative work needs to be coupled with narratives, if intended for others.

For the example above, one could look at it as a meaningless blob, and someone else could describe it as a run-time behavior with y-axis representing time. Someone else could have some other interpretation. So a narrative could help it fit it in the intended place

Not arbitrarily so. We don't have to throw our hands in the air and declare them infinitely ineffable.

Nor do we have to throw out everything that doesn't meet some arbitrarily high standard.
