So his perspective is no more “apostolic” than any fellow that claimed to understand the Gospel.
Can "any fellow that claimed to understand the Gospel" also claim apostolic succession and episcopal consecration at the hands of the same?

If we include St. Peter, Ignatius was the third Bishop of Antioch and the immediate successor of Evodius (Eusebius, Church History II.3.22). Theodoret ("Dial. Immutab.", I, iv, 33a, Paris, 1642) is the authority for the statement that St. Peter appointed Ignatius to the See of Antioch. St. John Chrysostom lays special emphasis on the honor conferred upon the martyr in receiving his episcopal consecration at the hands of the Apostles themselves ("Hom. in St. Ig.", IV. 587).
Wrong. He knew Peter and probably John and Paul personally.
His "Letter to John" is spurious; that's not the same as saying he never knew him.
Polycarp was definitely a disciple of John.
