STAR WARS sets are far less risky than any Super Hero set, this side of The Tumbler. For the most part, the most valuable STAR WARS sets are based on vehicles, while successful Super Hero sets (with exception of Tumbler) are valuable because of their figures. Maybe you should build a few and you will see the difference.
As for my completely incorrect logic...You think you have this all figured out, but you really have no clue. You think you are Spock, only dealing with logic and numbers. LEGO is more than logic. It is a passion and creative force unlike any Amiibo, baseball card or Beanie Baby. It's sad that I cannot teach you these things. You either get it or you don't. You can make money off of logic, but when push comes to shove, the person who "gets it" will have a distinct advantage over those who don't. This applies to any collectible or item that is resold.
I have seen people like you on this forum before and you treat it as a commodity, with really no respect for the product itself. Next year, you will be on the next forum, discussing the next hot trends in collectibles, but never really appreciating the collectible being discussed. Until you accept the fact that emotion plays a huge part in the LEGO world, you will never truly understand the opinions of many on this site.
