It can change. The reason why qabil is so rampant right now is because the government is weak and doesn't help its citizens at all. This lack of trust is what causes Somalis to rely on their qabil for a sense of security which then causes conflicts with other qabils because again, there is no law and order the government can enact since they are too weak.
Virtually every ethnic group was tribal before the modern age. The Japanese, Italians, Germans, Turks, Arabs, Finns, ect all constantly engaged in clan or state based conflicts all the way up until the modern age where one group finally dominated the others or they all collectively agreed to unite. Clannism isn't natural whatsoever for a nation state thus it needs to be gotten rid of if we want to see development.
