> the value the owner derives from the house is not dependent on the resale value of the house

It often is, instead. Eg the resale value of my flat increased because the area where I live became a better place.

What they mean is the day-to-day "value" of having a roof over your head, in contrast to your ability to make money by selling.

If the area around you is improving substantially, then yes that day-to-day value could be improved by better local shops, maybe a closer office building, nicer parks, etc. Generally stuff like that does not happen quickly though, and really big changes like magically teleporting from boring middle of nowhere to a vibrant cultural downtown don't happen at all.
