Look he is saying there is no "unconditional" solution, which is absolutely correct. There is a solution, which may work, or may not work, depending on the state of the world when it is applied.
That is trivially obvious though. Of course there is no solution which works at all times, in all circumstances, that is why any proposed solution has specified bounds. To take 5 pages of back and forth to arrive here with that result would be very disappointing indeed.
The salient point continues to fly right over your head.
That is that the cases where the count of faulty nodes can be conjectured quantitatively (such as MTBF failure rates for hardware components) does not include the trustless, decentralized, Sybil attacked applications such as Satoshi's PoW design.
My statement is fact:
There is no decentralized solution to the BGP problem. Period.
