I wouldn't say IKEA furniture is garbage, or comparable to some vibe coded mess that may contain who knows how many bugs and vulnerabilities.
IKEA furniture is obviously a trade off between quality and cost, but it does what it is designed to do.
Capitalism isn't just a race to the bottom - there are markets for products at all sorts of price points.
Maybe typical Supermarket produce section = IKEA is a better comparison than vibe coding = IKEA, although whether a tomato that tastes of nothing is really doing it's job is debatable.
