Actually I had this idea some time ago that market economy is just splitting central planning into small pockets that compete and die if they make wrong decissions.

It works way better than when all economy is centrally planned.

So it might be prudent to prevent companies from growing too large and integrating to much vertically or growing into multiple domains horizontally to prevent inefficiencies inherent in large scale central planning from comming back.

In my minds it's not VCs, it's CEOs of Disney, Amazon, Unilever and such.
