Maybe. If zoning is fluid and organic, you might get those. And they are nice things that many people value.

But, in existing zones? Maybe not - you'd have to convince people to change residential to commercial/retail. And changes to parking minimums, which always seem to screw up projects (they almost always require more parking than a "free market" would dictate).

That also means "those people" can walk into your neighborhood, and many are motivated not to let that happen.

I lived in an area that, for years, refused to let an old railroad track be converted into a trail because it would connect a working class area of the town to an upper middle class area via a miles-long footpath.

That needs a commitment to commercial space on the first floor and underground parking for tenants so that surface parking is available to customers without the need for massive lots. Builders who want to extract maximum profit with the cheapest construction won't go for it.

So, the status quo has to change. Not an easy job, but the rest of the world shows how it can be done.
