Mass/bulk producers will have an advantage for most products so long as mass/bulk production of feedstock is in the production loop, allowing them to achieve lower costs than home production through economies of scale.

Think about how/why home printing/copying didn’t put book printers out of business. That will be amplified, at least initially, by the need for multiple feedstocks to meet different desired product attributes.

We may see some localized production (e.g in copy stores and hardware stores) over this decade.

Probably some form of limited home production will catch on, where cost savings are not the primary consideration – hobbies, school projects, etc.

A small/cheap CNC machien would be much more flexible than a single-material printer – able to shape wood, plastic, maybe aluminum.

Further, I’m not sure I agree with all of the author’s critiques or conclusions. But it is undoubtedly true the world is in a mess and a that a good deal of that mess is the direct result of decades of neoliberalism.

Thus, I submit that today’s libertarians are in precisely the unhappy position that social democrats were forty years ago. That is to say, the Left discovered that much work and millions of dollars invested in social welfare did not produce utopia. Now, the Right must explain how its ideology did not give us Galt’s Gulch or anything like it.
