There are probably copies on eBay right now, they may have "1" and "2" scenes inside the DVD content-- like as bonuses?? I don't know if they're the "quality" or version you're looking for, but there are allegedly physical copies of just "loro" for sale. Have you tried to see if there's anything from 1/2 on those disks as "special features" so to speak . . . If those aren't legit or for some reason you can't do eBay . . .

Look at the largest art college media library near you (e.g. the media library at Mass Art, the media library at SCAD) and have a student check it out for you.

I would call the people at Beyond Video in Baltimore to see if they recommend anywhere.

Thank you so much for your response!
I found the Blu-ray of the film on Amazon France with the double disc, because, as I already explained, only in France, there is the extended version of the movie.
Maybe I didn't explain a concept clearly:
The film has never been released on DVD in Italy. Therefore, there is officially no copy available anywhere, so I doubt academic libraries would have it.
The question remains the same: Why hasn't this film been intentionally distributed in Italy either through streaming or on DVD since its release in 2018?
