To a certain extent it can, and this was an objective with the DASH work in 3GPP and MPEG. But the system and procedures have to be flexible enough that they encompass all the use-cases without compromising one in favor of the other. You do end up with a system which can support both a single-file-per-track-with-byte-ranges for on-demand and small chunks for live. There is nothing to stop you *using* small chunks for on-demand but the disadvantages of this mode are so significant (as I described) that it can't be the only solution for on-demand.
