How would it make sense? Have you seen how things are manufactured? Why would you want to make something harder and more expensive than it has to be? It's delusional to think that these things will work better in space/on mars than on earth.

Some metallurgy on the Moon might be easier - at least the atmosphere doesn’t want to react with the materials. For other processes, you actually want some of the atmosphere to do exactly that.

We’ll need to develop base industries from scratch for these environments, but, eventually, we’ll get there. The downside is that it’ll take at least multiple decades, if not more than a century.
