As far as I know, in the US eminent domain has similarly been used to "fight blight". You could argue that the property owner in those cases also had a choice by keeping their property in good condition.
"fight blight" has a broad term. In my town they blighted the Ferrari dealer to make way for a mall. Because, well once a Ferrari dealer moves into a neighborhood its all crack houses and ruin from there on out. Also a bunch of tidy, well maintained little brick bungalows whose owners just wanted to die in the houses they lived in their whole life.
No, it's not. With eminent domain, a property owner doesn't have a choice. Here, the property owner can pay the taxes due and keep the property.
