Complexity and cost aren't bad when they help produce something of value that we wouldn't have otherwise.

For $150 I can fly round trip from New York to San Francisco, on a massively costly and complex giant noisy metal tube with two blades sticking out the sides that are so strong you could put a tank on each one and the blades still wouldn't droop. Why does it have to be so costly and complex, if I could do something simpler, like take a bus? Well, mostly to keep me from dying. But also to carry lots of luggage, keep costs down, and get me there 15x faster.

K8s does provide great value (as a dev tool), but lacks value in production features, and its design is shit. So I wouldn't say complexity and cost are the downside; it's the lacking production value that's the downside.
