I disagree, zoning is very much needed. No human should be forced to live in an industrial area, for noise and pollution reasons if nothing else, those two uses (residential and industrial) should be well separated. There also a few other common sense zoning logics like keeping buildings at a somewhat similar size (e.g. not have skyscrapers next to a single story house, but have mostly houses, mostly midrize buildings, mostly skyscrapers, with the appropriate infrastructure/greenery needed), having appropriate park to density ratios, etc.

In the US zoning is abused to hell due to (sometimes historic, sometimes still ongoing) racism and NIMBYism, but that doesn't invalidate the whole concept.
