Roman Full Plate Armor?

[SigniferOne]

There were a lot of technological innovations that led to the development of a reasonably comfortable suit of plate armour that the Romans simply didn't have: water powered trip-hammer mills, the sliding rivet, etc.

I don't understand how these arguments are relevant. It used to be argued by medievalists that Romans (ancients generally) simply didn't have the technology to create full-plate armors, let alone segmented, riveted full-plate armors which Late Medieval knights sported. And here we have not only literary and possibly visual references to precisely such a thing, but Dendra Armor which was created one or two thousand years before the Roman time. So what do these medieval 'inventions' have to do with full-plate armor? Are you telling me that the Romans were somehow inherently unable to equip their soldiers in it if they so decided to?
