If the permanent Martian settlements are to do their own manufacturing, it seems that they would need both fusion power and nanofactories, or something equivalent. The type of energy sources and resource ores we use on Earth for manufacturing would probably not be available in any sufficient amount.

You might be right. I hope not, though, because that means it will take even longer to escape from the planetary cycle of overshoot and collapse.
Then again, it’s good to be ready for the worst and be pleasantly surprised if things turn out better than expected.
