Somalia as a nation has as much legitimacy as Kosovo or Biafra; most recognized nations today are formed on either colonial lines or previous unions and empires. Ethiopia is a previously-formed empire, UK is a previously formed union, but Somalia was struck up solely on colonial lines and even in 1960 we managed to defy that by unifying two separate colonial entities.
Before the late 1800s, there was no such thing as Italy----EVER! There exists no such state as Italy, as far back as the collapse of the Roman Empire, the Italians were divided as the Venetians, the Genovese, the people of Rome, the Sardinians, the Neapolitans, and the Sicilians among many other independent regions. The only thing that brought them together was sharing the same peninsula, same with the British peoples' - Italians just like their British counterparts recognize the huge diversity in their nations and the racism and division within its indigenous peoples'.
So, lets look back beyond the first Somali states in the 1960s. Has their ever been a unified force in the Somali peninsula that was dominated by Somalis and existed solely to govern Somalis or even strictly the Somali peninsula? No. And there is your answer. We lost nothing, and no time in experimenting with this new-age nation-state thing, it didn't work out, and its time to move on.
I propose Somali states based on cultural and geographic similarity, because clan states are flawed and ultimately laughable in this era and they bring up the question of shared regions.

Purple = Northwest Union
Green = Confederation of Mudug States
Pink = Barwaaqostan, it will also inherit the rights to Mogadishu since they are the most peaceful and productive people
Red = Southwest Union
Yellow = Waamostan, this hotly-contested and troubled region will be re-educated and isolated from all competing entities to allow the people to heal and lock away any grudges
Support the future.
