I have heard of YIMBYs but this profile of a vigorous NIMBY resident of California suggested multiple options:

To distinguish themselves from NIMBYs, the current generation of housing activists has adopted new “back yard” variants (YIMBY, “Yes in my backyard”; PHIMBY, “Public housing in my backyard”; YIGBY, “Yes in God’s backyard”) to declare how they are for things (everything, subsidized housing, building on church parking lots) that a NIMBY presumably is not. Politicians have piled on: In California, homeowners who are used to being catered to with a host of regulatory and tax policies recently woke up to discover that their governor, Gavin Newsom, told The San Francisco Chronicle, “NIMBYism is destroying the state.”

YIMBY has the advantage of being a clear and obvious alternative to No opinions on development and housing. PHIMBY looks better spelled out but could confuse hearers about whether it is FIMBY. YIGBY sounds like a religious or spiritual version of YIGBY.

A catchy and clear acronym could help make the anti-NIMBY case but it will not be enough on its own to combat the common NIMBYism present in the United States.Even with the concerns expressed about NIMBYs, they likely have the decided advantage in numbers and sentiments across American communities. Many residents want to protect their properties, views, neighborhoods, and investments from a variety of perceived threaters. It will be on actors who have the opposite point of view than NIMBYs to push sentiment and regulation in other directions. This is not an easy task, and this is true even in a state like California that needs a lot of affordable housing.
