I have to chuckle when people say the building could be "repurposed".
Here's the street view with the collapsed wall:

The "problem" with the building is that it was built for its intended use (grain silos, which can be seen in the exposed wall). And it was designed in such a way that the silos support the interior cross beams for the building.
So, the silos cannot be removed because, if they are, the roof and walls are no longer supported and the building would collapse on itself.
It's a similar issue like the old Maple Leaf Gardens in Toronto. The original plans were to "repurpose it" but they found out that the concourses and seating were actually holding up the walls of the building. So that why it ended up being used as a university athletic centre.
