Most reason why people don't involved in the buying of bitcoin is because of the transaction process its really stressing and it has so many procedure's, before now in my country if you want to buy crypto is very simple you transfer from local account or bank direct to wallet but you have go through a whole lot of process from one channel to another before payment is made and the worst of it is during withdrawal you will discover that the stress of withdrawing your money is a tough one. I believe this peer to peer can be redirect to channel through local banks or account to crypto wallet straight and make more people to involved in investment and trading. Or is there platform one can buy and sell easily without passing rigorous payment system? Please share
The problem you are discussing is what the government created by a way of banning bitcoin or regulating the operations of cryptocurrency in different countries. There are some countries that bitcoin is not banned but banks are not permitted to make any cryptocurrency related transactions. This has automatically made the people in that area to resort to the p2p introduced by the CEXs.
The p2p proposed by Satoshi in the white paper can only be accomplished I a decentralized way. But centralization has eaten deep in the people. So, the problem you are seeing is not created by bitcoin but external bodies. It is either you follow the hard way to buy bitcoin or you follow the easy way and sacrifice privacy.
