ELI5: How is it not possible for NASA to have usable spacesuits by 2024?

Elon retweeted a headline in which NASA said that a 2024 moon landing was unrealistic because the agency wouldn’t have working spacesuits by then. How do we not have working spacesuits now when we had them in 1969?

We do not have the technology any longer to make new Apollo era space suits, or even repair the ones we have. We have all the plans and drawing of them but we do not have the materials, skills and technologies to make many of the components and a lot of the components were bought from suppliers who no longer makes them. And the space suits developed for use on Skylab, Space Shuttle and ISS is of different designs which does not allow for the same level of mobility. They are made for zero-g close to a big spaceship with robot arms and carefully planned maneuvers. So we would have to radically change the design anyway to get something that can be used on the Moon.

But we also do not want to go back to the ancient technology of the space suits developed in the 60s. We have new communications technology, more computer control, better life support systems, etc. And when we go back to the Moon we are there for long missions, not the short ones that we saw in the 70s. So the space suits have to be repairable, quick to don for emergencies, and last for a very long time. These are requirements they did not have in the 60s. So even if we are able to accurately recreate the Apollo era suits they would put a big constraint on any lunar mission.
