You appear to define an Industrial Revolution based on cultural/society norms not technology. I disagree with most of your post because of that.
I will concede the plagues point, but had the Roman Administrators not been greedy & corrupt deviants, their Empire could have easily lasted until the Mongols came along eventually.
Whatever happened with “climate change” that caused Eurasian migration could have easily been dealt with had they built a wall (like Hadrian’s Wall) along the Prut or Danube River frontier and had viable armies (back to the corruption) to face them.
Public benefits such as a postal service, banking, education would have eventually morphed into Roman life had the continued with the mildly corrupt system they had in place in the middle third century.
Industrial Revolutions start with technology and Rome was light years ahead of everybody in their part of the world.
If you’ve ever been to Europe and have studied their buildings a lot of the technology they used doesn’t exist anymore and not because it’s obsolete, but because people lost that technology and the ability to replicate it.
Cement, door hinges, heating systems, construction styles to name just a few are examples.
It’s rather ironic that Roman aqueducts are still being used today. I guarantee you the same will not be said of anything our civilization currently uses, two thousand years from now. Well maybe pieces of Hoover Dam will still be around.
Our fall is mirroring Rome’s in more ways than one due to corruption.
The Romans were no more corrupt or deviant than any other people in history.
The Roman Empire began during the so-called Republic period, with the conquest of Ostia, and went on until just 39 years before Columbus set sail into the west.
BTW, the Romans did have a wall in Germany and on other frontiers. They served the same purpose as Hadrian’s Wall, limiting access in and out, and collecting taxes on imports.
