This is a wonderful idea.
If only he could make crafts big enough to lift whole tribes and their cows, it could solve the current problem in Kenya.
Imagine if all the Luos, Luhyas, Miji Kenda, Somalis (42 out of 44) left for a section of Mars, every Land grabber would have like a whole county to himself.
I can see Uhuru extending his family holdings in Kwale and the whole idea of rigging Mvurya in (54% vs 44%) so he can sign off more mineral rich land to some "offshore company" would be unhelpful to the cause.
The opposite is also true. If some people who cannot live with others because they cannot stand the idea of "being ruled", could be encouraged to move to a new planet with unlimited land; where the sand is Gold and god, perhaps we can solve this problem.
