The arguments in favor of an absolute prohibition, or an extremely circumscribed eminent domain authority are persuasive. The eminent domain process itself is unfair. As Jane Jacobs, renowned urban historian and a keen observer of urban redevelopment efforts noted in an amicus brief to the Supreme Court, "Condemnations generally benefit the politically powerful while the costs fall on the poor and politically disadvantaged."
My feeling is that (private-to-private) eminent domain is worthless. Screw it! Cities should advocate small scale development proejcts that fit into their neigborhoods and offer organic, human-scale densification and tax-base growth. There's a reason that big, totalitarian, top-down management proposals are incredibly unpopular . . . it doesn't work very well. It doesn't build neighborhood values. It alienates the very people who are supposed to benefint from urban planning: the citizens.
Look for more on this topic, as it's a quasi-libertarian red meat issue.
