One of the more fucked up aspects of eminent domain. City/county/state governments can nuke deeds by using eminent domain. It allows them to turn a plot of land, regardless prior restrictions, into things like dumps.

The fucked up part about it is they can also turn public lands into private lands with that same trick.

What's frustrating is we still need eminent domain for good. It's basically the only way to build railways and roads. It even ends up being one of the few ways to deploy things like district heating/cooling and new fiber lines.
