This sounds a bit strange to me.
I live in an underdeveloped country, but I work remotely for a fairly good web development agency. We don't have a lot of financial services/wallets here, so we had to go circumvent a lot of obstacles for me the money to get to my local bank account.
Does he pay you with black money? I find it hard to believe that a bank would have problems with you receiving income from a job, as long as it is legal and declared.
On the other hand, if at the end of the day you have to convert part of the P2P bitcoin to be able to pay in fiat, I don't see much difference to cashing in fiat, spending what you have to spend and buying P2P bitcoin with the rest, apart from the problem with your bank.
Are you aware of the fact that in some parts of the world less than 20% of people have access to the Internet? Somalia and Eritrea are one of the countries with the worst Internet access in the world.
No Internet means no ATMs and no card terminals in stores. To get money you have to physically go to the bank and request a withdrawal, or fill in a paper with the bank number of the person you want to send money to.
Can you imagine running a business where you work online and to find out if you've been paid by the client you have to go to the bank and stand in line to ask if there's money on your account.
We've been living so long in the world where everybody has a phone with a bank app and can move money around while commuting from work that we forgot how our parents had to do it when they were kids.
