The purpose of both for record keeping. While cuneiform and hieroglyphs evolved separately the foundation for both was rooted in the Mesopotamian system which is what the first Meso-Elites would have brought with them, not cuneiform, which they would have used pictographs that made sense to the local populations. Interesting to note Indus Valley civilization of the same period also used a system of pictographic tokens:
I need you to clarify something. You propose the Meso-Elite came to Egypt within a time-span of about 500 years prior to let's say Narmer...co-inciding with what is known as the Uruk-expansion.
During those 500 years, the script evolved from pictograms (what you show there dates to 3500 B.C., right?) to cuneiform in Uruk and from pictograms to hieroglyphs in Egypt even though you propose that there was an administrative presence which would have maintained the script of the homeland, don't you think? Let me ask you straight up...do you think there was a Mesopotamian ruling class which commanded Lower Egypt and was in constant communication with Uruk and took orders from there? That's what I call administrative presence.
So one alternative explanation is that the prevailing medium to record script was not conducive to cuneiform writing for example and so papyrus won over clay eventually which couldn't be etched and imprinted.
Another explanation is that, which is what I suspect happened, is that the Meso-Elite was never an elite. They were immigrants who brought with them some of their know-how and mingled with the local population. Out came the White Walls. This is a better model to explain partial cultural imports as opposed to an all inclusive cultural invasion which I still don't see.
In any case, if you want to prove/falsify the Elite theory I think you won't get around showing that specific Uruki genetic traits can be found in pre-dynastic royal human remnants. This is predicted by your theory.
