Back in the '80s, Baltimore considered seizure of the Baltimore Colts football team by eminent domain, and the Maryland legislature was contemplating enabling legislation to let them do that. So early one morning a bunch of moving trucks arrived at the facility, loaded up all the Colts' gear, and a convoy of trucks made its way to Indianapolis.
IIRC, news reports at the time said Baltimore officials found out about it and after some scrambling got a local judge to ORDER them not to move . . . but the convoy had already crossed the state line (beyond a state judge's jurisdiction) and they couldn't find anyone left in Maryland to serve the papers to anyway, so despite much gnashing of teeth, the Colts stayed in Indianapolis.
The point being - misuse of eminent domain to seize things other than real estate is an "iffy" proposition at best. If Richmond starts seizing mortgages or other financial instuments, financial institutions will stop doing business there, and anything remotely at risk will be moved.
