This is because the /32 subnet only allows a single IPv4 address and all traffic will go directly between the device with that address and the default gateway (If any) from a host perspective. The device would not be able to communicate with other devices on the network since he is basically alone and there is no gateway.
For p2p links use /30 or /31 but never 32
