Epoxy coated steel wouldn't help too much, the epoxy would crack with
movement and allow moisture in. And galvanizing is a sacrificial coating so
it wears out as it oxidises. So I agree with your statement that no modern
steel reinforced building would last 2000 years. But with a roman cement
mix and those basalt epoxy rebars they might have a chance.
