I think it is quite interesing that for Scotland being such a small country (relative to places like the USA) and for people separated from living there/that culture by multiple generations that so many around the world have this passion to celebrate Scottish (specifically Highland) culture.

Is there anything else that compares to it?

For those living in the Scottish Highlands it must seem very odd that all these people around the world have this great desire to maintain this connection. But because of it Scottish tradional dance, music, athletics, fashion, and crafts have survived and continue to thrive in a world generally obssessed by the new.

Sure a lot of "brigadoonry" , stories and myths, are bound to pop up, but that happens around any traditions and history.

The Scots have a reputation as engineers. Using what they had efficiently and building things to last. It seems their culture also is built last as it endures and spreads far from the highlands.

Cheers
