Yes, and I think that's easy to explain.

People always judge each other by the way we look and the interaction in CS:GO is no different from the real life.

So, the same way you become attracted to a guy or girl, the same way you relate to the person with amazing knife or rifle (may be you are unique, but this applies to the majority of people).

And when it comes to the karambits and their prices, they won't give you any "Status" if they would be so cheap; therefore, Valve made them very hard to get.

All in all, if you want to get the karambit cheaper buy it on DMarket - https://dmarket.com/ingame-items/item-list/csgo-skins but in case you don't care about the look just ignore it.
