I am all up for first principles thinking, which is what you demonstrated above. The problem with this approach, however, is that you have to think deeply enough to get to the very bottom of each topic. Your analysis didn't touch on the fundamental need of any democratic society to sustain strong economic growth. It's a well-known fact that destabilization of that growth nips away at democratic principles and ultimately leads to totalitarian governance. Just look a the role of economic instability in the Nazi rise to power [1].
So, yes, people may decide that we no longer want a certain type of companies. Heck, let's take it a step further - people may also decide that we want everyone to get a million dollars, no questions asked. But people are smarter than that, which is why we still have democracies.
