the Ichnographia as "theme park"
...the notion of the Ichnographia being used (perhaps for the first time) as a "guide map." Using the Ichnographia as a guide would seem ridiculous to most because the large plan has always been dismissed as a pure fantasy. It can act as a guide, however, especially if one is aware of the textual background of the plan, meaning the historical texts which describe ancient Rome.
...looking at the Ichnographia as an ancient Roman theme park--a virtual place where one can vicariously experience the ancient city as well as learn about the history of the city.
The themes Piranesi uses are numerous:
a. the Imperial genealogy of both the Bustum Augusti and the Bustum Hadriani.
b. the forward and backward "ride" of the Triumphal Way.
c. the military themes along the Equiria.
d. the numerous garden designs
e. the nemus Caesarum.
The whole typological catalogue is nothing but one variation on a theme after another.

I'm glad you found some useful information, and I hope it helps toward some resolution to how you see that reenactment (potentially) relates to predestination and psychology. I haven't been coming to reenactment from that angle, so I don't even understand exactly what you're seeing. (But that doesn't at all mean that I think what you're seeing is somehow wrong or misinterpreting.)
I'll try to briefly outline (reenact) how I came to see a strong relationship between reenactment and (some but certainly not all aspects of) design.
I began redrawing Piranesi's Campo Marzio plan with CAD in 1987. I've been fascinated with this plan since the late 1970's, and I saw the opportunity to utilize the automated drawing/drafting capabilities of CAD in (re)drawing all the complicated individual plans of the Campo Marzio, which comprise many repetitive units, and manipulating repetitive units is precisely one of the things CAD is very good at facilitating.
In the early 1990s I begin an intensive redrawing of the plan, and at the same time I became reacquainted with Susan Dixon, a friend from my college days who went on to get a Ph.D. in Art History, and her dissertation was on Piranesi's archaeological publications, of which the Il Campo Marzio is one. Together (via phone conversations) Susan and I begin speculating as to what the meaning of the Campo Marzio plan might be. Many theories were speculatively put forth, but reenactment was never one of them.
The second week of August 1997 I split my energies between doing research on the Campo Marzio and research on the philosophy of history as it might relate to my theory of chronosomatics. In Encyclopedia Britannica (edition 1969) under "Philosophy of History" there is a passage explaining Vico which, while reading it, made me think of Piranesi's Campo Marzio. There is also a list of 20th century philosophers of history and the titles of the works. Collingwood's The Idea of History is among these. I go to Barnes and Nobles that same day and buy Vico's New Science and Collingwood's The Idea of History. I read the passages in The Idea of History that deal with reenactment. It dawns on me that I've been doing a kind of reenactment by redrawing Piranesi's plan.
Thursday, September 4, 1997 (coincidentally the day architect Aldo Rossi died) I find Plattus's "Passages to the City: The Interpretive Function of the Roman Triumph" in Ritual (1983). I finish reading the essay Friday night. Saturday morning I watch Diana's funeral, and it quickly hits me that I am watching exactly what I just spent the last two nights reading about. Since Piranesi himself delineated the path of the Triumphal Way through his plan of the Campo Marzio, I begin to wonder whether Piranesi too was playing some kind of reenactment game in his redrawing of the large urban plan.
It is after this point that much of the prior ten year's work begins tightly piecing together, and the notion of reenactment also aids in better understanding what information I collected further in research.
For me, reenactment was a learning tool, albeit for the most part a tool I didn't even know I was using. For Piranesi, however, (and this is what I've come to understand) reenactment was a design tool, specifically an urban design tool, whereby he generated an entirely new rendition of Rome. A Rome, moreover, that is essentially a conglomeration of many specifically themed environments, i.e., themed environments that relate exactly the history of the very places where Piranesi positioned his new designs. This is why I say Piranesi's Campo Marzio is not a reconstruction, rather a reenactment. By all indications, Piranesi was very conscious of the play of degrees of separation that reenactments involve.
Piranesi also (re)designed the city of Rome as a double (history) theater, namely the double theater of Rome's Pagan and Christian existence.
Re: a Bemused Tadao Ando observation
Interesting how you relate the Museum of Literature to a kind of themepark. It could easily be said that Kahn's formal playfulness was inspired by Piranesi's Ichnographia Campi Martii, an ultimate plan of an ancient Roman themepark if there ever was one.
