Does mapping cultures to real world cultures in worldbuilding feel like a sort of cop out?

I don’t know if I’m gonna have people downvoting me for this, but I’m gonna mention D&D because this is something I’ve come across more and more. The Dwarves are Scots and the Elves are Welsh. That’s the basic premise. I think the reason why I’m disappointed in such a choice, is how little they stray from the sort of mold. Like the Dwarves are seen as being hard headed and hot tempered. The Elves are seen as being somewhat mystical and they tend to talk in riddles. <br><br><br><br>That being said, I’ve noticed a lot of things in worldbuilding tend to be connected to real world cultures. I think the Drow are inspired by African culture, but a lot of the lefthandedness comes from that they tend to wear their swords on their right. <br><br><br><br>I guess I’m sort of curious, because I know when I was worldbuilding some of my settings, I wanted to draw inspiration from real world cultures, but also feel like I’m breaking the mold a bit while doing it. I think the closest I got was I had a race of beings in one setting that was inspired by Japanese culture, but with the exception of a lot of them having black eyes instead of brown. That being said they were allowed to keep their own culture in the setting and they weren’t used as a plot device.
