I was tempted to help you out on this one but thought not knowing enough to bring up Kelo vs. New London on this topic truly showed your lack of knowledge and understanding of a part of the topic you are trying to expound. That you could go all day discussing this topic, including eminent domain and not reference Kelo vs. New London shows you are merely doing the cut and paste thing and lack any genuine expertise on the subject.
Any good liberal like yourself would be familiar with the Supreme Court case
Romer v. Evans 517 US 620 (1996), when a Colorado law preventing protected status for homosexual and bisexual couples was struck down. But the precedent was set, that an action by government must serve a legitimate state interest.
Another case was
United States v. Virginia, 518 U.S. 515 (1996) which stuck down Virginia Military Institute's admissions policy regarding women. It said that the purpose for government's enaction of policy or any action "must be genuine, not hypothesized or invented post hoc in response to litigation."
Kelo did not establish any kind of reinterpretation of the 5th Amendment. Most of the time, eminent domain is exercised by state and local governments, not by the federal government. In this case, New London attempted to re-purpose the lot in order to boost the city's economy.
Your interpretation of Kelo is flawed, as is your understanding of imminent domain. Prior to Kelo, only 7 states had laws prohibiting the use of imminent domain for economic development, however, after Kelo, 44 states have enacted similar laws, essentially nullifying the ruling.
Your argument is invalid.
