I think the key words in that are "for public use". Traditionally, that had been interpreted to mean actual use by the government (roads, schools, etc.). The question is 1) Are public good and public use the same thing? and 2) If so, is an expanded tax base considered public good?
The other key words are "just compensation". This would have to include sentimental value and pain and suffering involved in moving as well as having to cultivate new relationships with new neighbors.
As someone who is in the process of moving right now, I sympathize with what you said. However, I disagree. the "just compensation" should be whatever the property's fair market value is.
