I don't know on which basis you are saying it as fake P2P trading. I have done many transactions. And also called to the buyer or seller many time.
According to me the person are real who trades with each other. And they do trade in local currencies from crypto.
I think without interaction of third party it is more risky.
To clear you more, before you're eligible to transact on Binance with their supposedly P2P option, you must first be a verified users on Binance with your real identity been exposed to them through there kyc procedures. Next although binance needs your approval before coins are been released to a merchant on the platform still that can be done without your approval if there was to be a valid appeal and it was confirmed that you have received the funds without approving for the coins to be sent to the merchant account by the Binance system.
To cut the story short, Binance ecosystem is built centralized which means, all other products that binance has to offer which includes their P2P products is also centralized. While you are actually trading with another users still you aren't receiving the full benefits of a P2P system which is meant to be total decentralized and there are better option out there if you want to enjoy total decentralization.
