If we're going to play the Either Or game, here's my play.
The 2008 crisis is on a long list of examples of how corporate efficiency harms me.
Governments have a mandate to benefit the public. Conversely, shareholder models encourage exploiting everything they possibly can (for shareholder benefit), corrupting government processes, harming the public and harming the corporation itself.
Instead of the Either Or fallacy, I suggest good-faith examination of actual harms and good. Governments (inc LEO) and corporations famously improve outcomes, when meaningful transparency is mandated, corrupt processes aren't hidden and ethical+competent overseers can pull the needed levers.
