Your argument makes no sense. Why on earth would the power problem be reduced when crossing from one socket to another, rather than from one die to another across an interposer?
As long as we are demanding the same things (same level of performance, same degree of snooping) from cores in a single socket and cores across multiple sockets, the socket communication is strictly more expensive than the on-die or through-interposer communication.
