The post I replied to logically argued that people are not harmed when their community improves and they are priced out and forced to move. (Note, I never claimed they were illogical, but instead that they were "too logical" Pure logic will not explain why people feel the way they do, because people are not always logical).

They then ask:

> Can someone explain what this description misses and where the harm comes from?

In answer, maybe no harm is actually done. But even so, people will perceive that they have been harmed. And in the larger context of this thread, that is why people are sometimes unhappy with their community being improved, because they believe it will price them out and harm them.
