No. In most American suburbs you can get more density by taking 2 single family homes and replacing them with one 6-plex. You’ll also have more open space, because a 6-plex takes up around one single family lot. Especially if the 6-plex can be 4-6 stories tall. Everyone can have more (private) interior and more (shared) exterior space if the neighborhood allows a little bit of density.

As a bonus having more neighbors means things like grocery stores within walking distance become good businesses, so you need a car dramatically less and less space needs to be taken up by parking lots.
