You and your neighbors aren't obligated to make as much space for them as needed, you just shouldn't have the power to stop people that would like to make space for them. Zoning changes don't obligate someone to sell their house and build a duplex, they just let someone do that if they want to.

Zoning laws make sure a community stays as the community desires. A community bans large apartment buildings for the same reason they ban power plants; construction benefits the property owner at the detriment of adjacent property owners.
