[Parcel Zero] costs CityDAO money ($100k annually, according to CIP-112 )
This is incorrect. The money requested in CIP-112 is unrelated and makes no reference to annual costs other than the $2k annual carrying cost estimate that @Fugyeah (and/or @fugyeah1) came up with.
That said, if the DAO doesn’t want to fund Parcel Zero efforts directly, this could be an alternative mechanism to raise related funds. I think this may need to specify that funds from the sale would be transferred to Parcel Zero NFT treasury.
I think Parcel Zero NFT holders would also need to have a say in this though, considering the impact on the Parcel Zero NFT License Agreement.
