What's the of value owning a bank account you can't take a withdrawal from?… at the moment.
Microsoft didn't pay didn't dividends… until they did. Apple paid dividends, stopped, then started again. If you knew about where they'd go, would you object to buying them before they started paying out?
Amazon hasn't ever paid dividends, but would you object to owning AMZN? Especially if you purchased it in (say) 2011.
Total Returns = Capital Appreciation (CA) + Dividends (D)
For most people saving for retirement is the primary thing that they're putting away money for. For that you want the biggest pile of money you can get for when you hit 65 (or whenever). Whether you can get pile with just CA (like with AMZN), or with CA+D, is irrelevant at the end of the day.
It's not that dividends are not important—they can be a (big) component of TR—but fetishizing them like there's no other way to build your retirement pile is short sighted.
AMZN may eventually pay out dividends, but until then you can own a piece of a company growing by creating value, and be part of the ride of rising value (represented, loosely, by a rising stock price).
