I suggest living Friday to Friday then, and diversifying a bit. Surely, no one lives week to week on the dividends, unless they are beyond messed up...
What if they live in a developing country?
It doesn't matter how much you earn or need or spend.
The whole point is that you should be able to save at least "one cycle" of money, as a fallback in case the next cycle gets delayed.
So if you live off your dividends, fine, but you should save at least one week of them, to be used in case next week comes later.
That's so obvious and natural I fail to see how can you miss it.
