I spoke with someone yesterday who lives in Nigeria, they were moving to Rwanda and needed to pay a deposit in advance. They were unable to pay via MoneyGram, Western Union etc. - one provider offered to handle the payment and requested many documents for a few days and in the end rejected the transfer. This person then had to send money to a friend who lived in the US who then forwarded it to Rwanda. This experience made the person feel isolated and outside of the system. This is an anecdote however my guess is if you think PayPal is "good enough" you don't live in a country that is marginalized by the status quo payment system.
