Zoning has nothing to do with separating uses. It never has. In Seattle, for instance, you absolutely can put an apartment building next to a pig farm. Nobody bothers because the market isn't interested in doing that. That also isn't atypical, zoning has never been used to pad uses away from each other like you see in Simcity.
Seeing the sky and getting sunlight are also very suspect reasoning. It is darn near impossible to find real problems there that zoning prevents.
Zoning also doesn't limit damage or impact earthquake survivability at all. Except - where zoning prevents you from building new buildings, it preserves old unsafe buildings. Without zoning, more of those buildings would be replaced with new structures that are safe.
There's no dystopia zoning is preventing. Most of the comments I see like this have very little understanding of what it does.
