I remember one comic where he arrested a fellow Judge for torturing a false confession out of a suspect, and then arrests that suspect for admitting he had some table sugar in his kitchen. Still not as funny as when he arrested himself and all his friends for a petty noise violation on Christmas.

I'm pretty sure Marx had some things to say about "treats" (not the "opiates of the masses" and whatnot, but the genuine enjoyment of and engagement with life and good things).

The less you eat, drink and read books; the less you go to the theatre, the dance hall, the public house; the less you think, love, theorize, sing, paint, fence, etc., the more you save-the greater becomes your treasure which neither moths nor dust will devour-your capital. The less you are, the more you have; the less you express your own life, the greater is your alienated life-the greater is the store of your estranged being

Humans are genuinely designed to like and seek out foods with sugar (though the modern refined version is absolutely disastrous, I agree), and foods with sugar/sweetness exist in nature all around us. Just like how most humans (and even some animals and plants) have an appreciation for, I dunno, the beauty of nature and art and music. Similarly, coca has its own history within the indigenous peoples of Latin America (as do other addictive substances, or substances that get refined to such an extent that they become addictive because of capital and capitalism). Sugarcane has a long and delicious history without being refined into white sugar, and if you've ever had sugarcane juice it's absolutely delicious.

I'm not saying there shouldn't be limitations on things that can take on addictive and harmful qualities- because there absolutely should be (sugar, coca, and other such drugs being around the top of that list for needing considerable management- though sugar certainly can't feasibly be just erased from human culture within the foreseeable future- hell, it's part of our biology, it's literally how our bodies are fueled).

That may be a fairly hot take for some people here, but I could do a slightly cooler one with the treatbrains that simply must blast out high bass floor-rattling BWOOMBWOOMBWOOMS well after midnight. Unlike the sugar, it instantly becomes everyone's experience in a wide radius.
