Buying and selling cryptocurrencies without the involvement of a third party or intermediary is known as P2P transfer. While peer-to-peer (P2P) transfer allows users more control over the process, it's important to remember that without a third party to broker the sale, peer-to-peer transactions come with some hazards.
I don't know what you mean by that P2P transactions come with some hazards, but just to mention that even it comes some hot risks, this kind of transfers (in the crypto industry) open the door for many trusted sellers to build their own business without the need for a third entity to confirm the transaction (blockchain do it very well). Some of them already running their commerce services here in bitcointalk forum.
About country regulating crypto transfers, this is far to be just to curb/forbid P2P transfers. On the contrary, it can help secure them.
However, crypto regulations will surely limit P2P transactions because regulations would also allow banks and monetary institutions being involved in this process.
