Anonymity doesn't matter
This is going to be news to countless social historians of the religions of the ancient Mediterranean basin who investigate archaeological and textual work without always knowing the specifics of the exact agents involved. Indeed, these historians are investigating the society that shaped the agents, even if they do not know most of the agents’ names (and all that this means).
They collect, analyze, and interpret evidence from a variety of sources—monuments and tombs, literary texts and shopping lists—in order to learn something important about the socio-historical circumstances in which people, like Paul, lived, moved, and had their being. The historian of antiquity, then, can learn much about the past from the ‘Letter to the Romans’ whether or not that text was actually written by Paul.
Here is the takeaway point: even if we grant that the books and letters of the New Testament are anonymous, we can still gather important historical information from those texts. Anonymity of the sources is not a death knell for historical studies, and should not be used as some kind of sweeping indictment of texts. We can know what happened to Jesus and his disciples two thousand years ago, using the New Testament documents as our sources.
Part of Hengel’s argument is that the authorship of the four gospels was unanimously attributed to Matthew, Mark, Luke, and John by the middle of the second century, and the only way for this to have happened was for the church to have known for quite some time who wrote the Gospels. If the authors’ names were truly not attached to their writings, multiple names would have been attached (as is the case with Hebrews).
To state it simply: if nobody knew for six decades who wrote the Gospels, the second-century witness wouldn’t have been unanimous. Rather, it would have been highly contested, and we’d have records of that. Instead, we find the traditional names as the only names.
This is especially significant when we realize that the Gospels spread throughout the Roman Empire as Christianity exploded onto the scene, and yet everywhere we look, the same four names are attached to the same four gospels. The ancient world was obviously not as well-connected as we are today. If people in one area arbitrarily attached the name “Matthew” to the first gospel, it would be an astoundingly rare coincidence for ALL people in ALL other countries to do the same. And yet in different countries throughout the ancient world, “Matthew” was always attached to the first gospel.
Craig Evans adds an even stronger argument. He states, “In every single text that we have where the beginning or the ending of the work survives, we find the traditional authorship.” In papyrus 75, a papyrus from the middle of the third century, we read “on leaf 47 (recto), where Luke ends (at Luke 24:53), the words εὐαγγέλιον κατὰ Λουκᾶν [“Gospel according to Luke”]. Below these words is a blank space, the equivalent of two to three lines. Below this space follow the words εὐαγγέλιον κατὰ Ἰωάνην [Gospel according to John and then the opening verses of the Gospel of John.”
Evans summarizes, “There are no anonymous copies of the Gospels, and there are no copies of the canonical Gospels under different names. Unless evidence to the contrary should surface, we should stop talking about anonymous Gospels and late, unhistorical superscriptions and subscriptions" (Craig A. Evans, Jesus and the Manuscripts: What We Can Learn from the Oldest Texts page 53).
It would have been nice if there were ancient publishers that had statements of authorship and dates of writing, but there weren't. Rather, we must rely on historical evidence, but in the case of the Gospels the evidence is ample. We can comfortably believe that the traditional authorship of the four Gospels is accurate, and that means Matthew, Mark, Luke, and John were in a place to know who Jesus was, what he did and what he taught.
Objection A - Widely attributing a text to a specific author still doesn't mean that the named person actually wrote it.
Historian C. Fasolt argues that Paul’s letter to the Roman church is helpful as a historical source “only on the assumption that it was written by Saint Paul.” Mike Licona, in his book The Resurrection of Jesus, notes historian M. S. Cladis’s response to Fasolt:

We know who wrote the Gospels
Martin Hengel makes the argument that titles like “According to Mark” were used much earlier than previously suspected (Studies in the Gospel of Mark 64–84). These titles were added sometime before the end of the first century, prompted most likely by the presence of two or more gospels that needed to be distinguished.
