Your point about how Netflix and the like are quite the opposite of short term profit maximizers is a very interesting one, because they apparently are not what people expect when lamenting the absence of long-termism (otherwise there wouldn't be much absence to lament), quite the opposite actually.

So what is that difference? It must be long term bets vs long term stability. A long bet can only be consumed in the literal sense, by selling, until there is nothing left. Whereas a dividend producer will keep producing until failure. It's almost like give a fish/teach to fish. A good portfolio of bets may well be more profitable overall than a bunch of dividends producers (and thanks to the market, we can cash in on those bets at or own pace! (and even bet on greater fools, but that's a different story well deserving of double-nested parens)).

But in the context of retirement, there is one important difference: the cashing in of bets forces us to think about our mortality when we plan our payout (no matter how formal or not the payout plan is), whereas with dividend producers this is only an optimal (even if important) optimization.

With a sufficiently wide spread and high volume, you could realistically live off whatever meagre or fat harvest your retirement package provides each year, and leave all dreams and worries about valuation to your future inheritors. It would not matter at all wether you'd live five years into your retirement or fifty.
