The FSSP and ICK are both vulnerable. However, they have a lot of leverage in the U.S. because churches function independently of the state, but are protected by civil law from the predations of a wayward hierarchy. Both of these groups were established under legal charters with the Catholic Church in Rome, and in the U.S. they typically operate in apostolates where the church properties are owned by their respective organizations or by non-profit corporations established under state law. This means they are likely to prevail in any dispute that ends up being adjudicated in a U.S. court.

If the ICK is really being shut down in Chicago, their most likely course of action is to sell their property and use the proceeds of the sale to buy or build a new headquarters in another diocese. They may even have all the legal standing they need to sue to Archdiocese of Chicago to recover the cost of the restoration work that has been done to the shrine up to this point.

This is a bit of inside baseball knowledge, but a rather prominent example among Traditionalist circles is what happened to "The Nine" that got kicked out of the SSPX due to their disagreements with Abp. Lefebvre and the SSPX about the increasing accomodations with the Vatican as to the liturgy.

The Nine vs. Lefebvre: We Resist You to Your Face. Written in 2008, it serves as a recounting of the events by the late Fr. Cekada, which does include discussion of property and legal issues.

Unfortunately the location is just on the edge of "civilization" on the South Side (63rd and Woodlawn). The University has extended its reach a little bit, and the Obama library will be just a little bit east, but I don't see a giant, half renovated church in that location as a desirable piece of real estate. I also don't think the ICKSP will want to initiate a lawsuit with the Archdiocese, but would rather take a low ball pay off if it comes to that. Alternatively, they can keep the church, hoping for happier days down the road.
