I'm not doubting the potential of Somalis to organize and get shit done, but the conditions – since this is very much going into different dimensions. A big operation in that politically non-transparent environment, being at the mercy of the rulers, with no specific laws, as you mentioned, is a problem. It can work, though.
You have to ask how other countries are able to start private ownership of these types of resources in the past.
There had to be a transition from when the state and fiefdoms owned everything to private entities.
No state or incumbent interest group (local clans) would give up ownership easily even it it'll benefit them years in the future.
They'd rather choke on a seed today than plant it in hope of gaining a larger harvest tomorrow.
In most cases historically, the only way others passed the transition is because private capital ended up with more political power than those that were holding the resources hostage.
A large organized investment group could potentially have way more bribes and resources to throw around than the current clan leaders and elected officials today.
If incumbents can buy hundreds of hardcore supporters then a serious investment group would be able to hire thousands or even buy out their backbone supporters.
This is the only way they can gain power and draft their own laws that'll protect their property rights in a transparent open way.
