You don't need a super skyscraper that's more than twice the height of the next tallest building in OK to address affordable housing.
Not a unique tower that has never been built before, and will have an absurdly high price per square foot.
Hardly anybody on HN wants to live in "the sticks" and you can build houses there pretty cheaply.
Housing prices can almost always be solved by moving, but people don't want to do that.
(To be fair, they're usually talking about moving from single family homes to allowing small apartment buildings of 4-20 units, not moving from single family homes to towering skyscrapers.)
Among countless reasons not to build something like this in Oklahoma City, the place is basically nuked by tornados every so often.

Developers take a big swing sometimes, sometimes to get interest in their proposals ( the internet likes it, so my local counsel will have to approve it ), sometimes to get attention from other partners to do big projects together. This may be a portfolio piece, even if never completed as proposed here.
I don't know much about OKC but a certain musical theatre work has me very interested in the wind loading studies for this building.

Building 1800 units of luxury high rise homes costing millions per unit isn't how you combat high real estate prices.
