Glamour and housing is the true endgame.
Only a bit more seriously (I was dead serious to begin with), a lot of housing items are a horrible pain in the neck to make. From items from Canals and Heaven on High now, through things you can spend literal weeks trying to get from retainer ventures or airship and submarine ventures...
They're expensive because they take effort to make or get, and there's demand. It's v. simple logic.
