Compensation had nothing to do with this ruling, that part of the 5th amendment was not touched. What this ruling did was change the definition of "public use." In the past that meant roads, schools, bridges, municipal utilities, etc. Now what this did was to add tax revenue to the definition.
Much the same as how the antis have gotten people used to the idea that private businesses are actually "public places."
A park is a public place - a bar is not. A road is a public use - condominians are private use.
I read that if they come for my house and property they have to give me compensation. They can't just kick me out on the street.
