my pt was that the construction of the relay network might have been a knee jerk reaction to the same "large miner large block attack" FUD that has been spread around by the Cripplecoiners.  it's author is a BS employee after all. it's only been around since Sept 2014.  i'm not saying that the relay network has been bad for Bitcoin; it may even have been good.  except that it is encouraging this non-verification scheme for tx's which as you say, may be gamed and has contributed to quite a perversion in analyzing this particular attack and was never visualized in Satoshi's original ideas.  perhaps it is not necessary to exist.  that is not to deny that it does exist and we need to adapt to it's presence.
