Zoning means central planners literally draw a map saying what goes where, and generally make all kinds of aesthetic decisions to go along with it. There is a big gap between that level of micromanaging land use and regulating against nuisances.

No, since this alternative allows for an apartment building with a couple of shops on the ground floor (normal in most of the world), and any other reasonable mixed development.

No one is suggesting heavy industry should be allowed in a residential area.

A set of local laws that says "heavy industry isn't allowed in residential areas" is a zoning code

It's a planning / permitting code, but the distinction from a zoning code has already been discussed in this thread.

And to quote one of the other commenters in that other part of the thread: "That’s zoning with a different name."
