It doesn't make sense that some of the most valuable land (Manhattan) is sitting empty. The THREE block long site south of the UN is clear evidence of real estate dysfunction. It's not even rehab development, it is literally a vacant lot. How is that possible? There's a whole slew of articles out there about this specific lot if anyone is curious. It makes total sense to me to go balls to the walls and activate or re-activate unused or underused lots and buildings. There is space to be found everywhere. The only issue is that this identification does not solve the real problem of can the government (the city) actually operate quality housing at cost that is not NYCHA? We don't want more NYCHA. All we have is the housing lottery right now that is going away as 421a ends anyways, it begs the question if a new government run system is required, but that presents many, many issues of its own. The alternative is identify these plots and lease or sell them to developers which would still create more housing which is good.
