I'd say only if I have direct control over my sims' habits, but... I'm afraid that if they ever introduce more autonomous behaviour to TS4, even if it comes with options, it will end up just as broken as everything else in the game (if not from the start, then wait for the next monthly patch). Suddenly you'll have slobs taking out the trash autonomously, lazy sims jogging as part of their morning routine, everyone always being confident from brushing their teeth all the time even though you'd prefer them in a different emotional state, and absolutely nothing you can do about it except turning autonomy off completely.
I'd rather my sims stop doing certain things autonomously, especially those that cost money. It's so annoying when a doctor randomly decides to dump a patient for a quick meal, and the money for that meal gets substracted the moment he thinks about it, instead of when he actually opens the fridge to get it. And no one needs as many drinks as my sims order when I leave them alone at the bar for five minutes.
