Somalis had wage labourers, in majerteen society for example and it was similar in western galbeed/harar and waqooyi.
Servants and slave were mostly used as guards and attendants, not really for production.
I am assuming the same or similar wage labour set up existed in Benadiri coast alongside slave labour. So i don't see it being difficult transform this into industrialization.
I also think we didn't lack capital either unlike the Madagascar crown, the Majerteen sultans and the city states were pulling in large sums, and we had an increase in non-agricultural workforce and town population due to the surplus food production in the mid-late 1800s.
Somalis had more effective transport caravan system that could be transformed into road structure if needed.
I think Somalis outside of Egypt was at the best position to industralize out of Africans.
Europeans never approached Somalia like they did with Madagascar and Ethiopia, they approached us with the intent of dismantling our commerces, destroy our cities and take control of our land resources. They didn't come to help or aid our development
