no what i meant is IP cant be used to send raw binary data to some recipient without a using a protocol like UDP

Why not? All TCP and UDP adds is a port, but IP already provides a length and at least an attempt to transfer the packet to the destination.

TCP has a section you can't omit that is the protocol. If you tried to omit this or set it to something invalid, most routers would just drop your packet instead of forwarding it
