Dead wrong, and indeed that is the difference to crypto.

If you own all Bitcoins in the world, it is worth nothing and your net worth is zero. If you own all stocks in the world, you can direct all of those public companies to pay a large chunk of their profit to you every month in dividends, and make those companies do whatever you want them to do (research a way to build a Mars colony, or build better fusion reactors or pay off politicians to do your bidding), which is real power and real wealth.
