Make sure the same argument doesn't apply to any of the other countries with space assets!
Having been part of a student satellite program, and having subsequently built my career on it, I can tell you that there is nothing more efficient at teaching students than giving them a bunch of money and telling them to build a satellite.
This satellite will be operated for many years by many students who will learn practical knowledge about satellites.
Not sure exactly how essential indigenous Earth Observation capabilities are for Botswana, but Botswanan engineers who worked on it and their university would actually be pretty well placed for future collaboration with low cost satellite component manufacturers in South Africa...
