An interesting fact that came to mind while reading this paragraph.
Until1975, fifteen years after the independence, one could still travel from Cameroon/Africa to France with only a passport; there was no visa requirement.10 years later, it was still possible to use your CFA Francs in some places in Paris, or exchange them for French Francs at no cost.
What it important to remember is that colonies were populated by millions of European settlers who emigrated with their families to take advantage of the opportunities in trade, business etc. These laws, I suspect, served the purpose of helping them to make business.
The African economy was much freeer and expectedly, booming like never before (and sadly, in most cases, also after). For the first time, many indigenous Africans could experience social mobility and be part of the new emergent middle class, and in general, everyone's standard of life improved. Cameroon's gdp in the early 60's was higher than Singapore's, South Korea's etc.
How times have changed!!
What do you think happened to the settlers after the independence?
