In a sibling comment, I point out that increasing long tails are not incompatible with overall mass centralization.

Relevant to your comment, increases in 3D printing capabilities have not translated into a reversal of manufacturing centralization in China’s favor.

That centralization continues as instability (often defended as an attempt to act against centralization) has perversely disrupted and pulled back manufacturing investment elsewhere.

As an individual, you may be able to do more, or choose from more niches. Even as the vast majority of resources and impact flow to fewer entities by volume.
