In other words, peep to peer consist of more work for a trader. Traders don't have much time to sit and talk to the person on the other side of the trade.
From my point of view, it's not viable.
You know, you should really look up peer-to-peer trading first. If it weren't viable it wouldn't be growing. And if your country banned Bitcoin, you'll be glad for P2P.
I do agree, it does involve a fair amount of hassle initially, or when trading with an unfamiliar party. For example, a first-time trader on Localbitcoins that you'll ask to verify first, or a trader who cancels the trade, or takes forever to make a payment.
But you don't have to sit down and talk to someone on the other side necessarily. The majority of my trades on P2P are automated. I either take an offer, complete it rightaway or I put up offers, and people take them. Bitcoin is escrowed. Only thing is to wait for payment to come through.
