alt Hacker News> a great tool to allocate resources efficiently
Sorry but... WTF are you talking about?
It rewards self-destructive behavior in favor of short-term gains. Shareholders have *zero* commitment to the companies they buy shares from and will happily switch their entire portfolios on a whim. It's essentially people chasing the new shiny thing every single day.
Let's not forget it's a known fact that people with insider knowledge will profit over everyone else.
How is that efficient in any shape or form?

You're basically explaining one of the reasons stocks are a horrible idea for distributing resources.
It has nothing to do with whether or not it's central or distributed, it's merely the incentives they create. It's essentially Goodhart's law on steroids.
Depends what you compare it with. I grew up in the post soviet union. That system allocated resources to various monopolies who were too big to fail. Turns out allocating capital based on who can make things that people want/need to buy, and do it with a profit, multiplies said capital way faster. From this point of view, over time your initial base grows into all kinds of industries etc. That's probably why the USA won the cold war.
