When you buy a stock, you're not contributing it to the company's productive use. If I buy $1000 of MSFT, Microsoft doesn't get an extra $1000 in their bank account to invest in their business. That $1000 is going to another bettor to settle his previous bet, and at some point in the future, I'll sell and get an unknown amount of money to settle my bet. Just because historically betting on the stock market has been +EV doesn't mean it's not still gambling.
