What are you going to use instead?

You somehow need to organize screen updates -- that is, when the
contents of the screen change.  You have to describe the change
somehow, and attach a time stamp to that change.
That's exactly what a frame is.

A video is just a sequence of screen updates.  No more, no less.
As every update is a frame, a video has to be a sequence of frames.

On a side note, time stamps don't have to be regularly spaced at a
fixed frame rate.  Some video codecs support variable frame rates
and/or frames with arbitrarily spaced time stamps.  FFmpeg is able
to handle and create such video.
