The issue of letting consumers choose the worse product is that the good products get pushed out of the market.

Grocery floorspace that was once primarily staples and whole foods is mostly now junkfood.

Proper razors have been replaced with disposables.

Skincare & toothpaste products contain sodium laureth sulfate , which lathers well, but causes mouth sores and skin irritation.

Letting consumers choose usually ends up optimizing superficial and sometimes harmful traits.
