Of course it exists, what are you talking about? Anyone that wants to transact on-chain can do so at any time.  

The network is and will continue to be P2P. Show me an example of a peer of the network not being allowed or requiring permission to transact with another peer. 

The elephant in the room is that not everyone will end up being a peer. Bitcoin is scarce, blocks pace is scarce. This is not a new revelation.
