Peer to Peer transactions and trades are good for privacy but people will need to have deep knowledge on how this trade type works and how scammers can exploit it to scam naive newbies.
It doesn't ends there, people can't even tell the difference between centralized and decentralised crypto platforms this days, when a platform overs a P2P service they go ahead and start using the platform, my point is not all peer to peer platform are to be used, what is the use for P2P when they ask you to pass KYC verification?
Most of people will choose convenience than privacy and if it is not mandatory, no other choices available, they will choose things that can bring convenience, not privacy. I don't expect banking restrictions will increase P2P transactions too much.
Privacy isn't even a thing here, if a peer to peer platform can bring convenience to their users without asking for any verification then its all we wanted, banking restrictions won't indeed increase P2P transaction, because too many people are fine with centralized entities even while Bitcoin is a decentralised digital coin.
Many people in crypto space still use and trust centralized exchange today, for their own reasons that I don't get, even after all the hacks and rugpull from different centralized exchanges in the past, why haven't people abandoned centralized exchange? The convienece of using a centralized exchange I guess, and some will say its because centralized exchanges are best for trading and volume wise.
People have their rights to choose and I bet that they will choose to use KYC platforms over decentralised or P2P platforms.
