I thought that luxuries was referring to stuff like haggis, woolens, Roman coins, ....
Haggis is always good for a laugh from the uninitiated, but it can actually be delicious. Scottish smoked salmon is considered the finest in the world. As are their adult beverages, which you seem to enjoy, and I used to. That being said, aside from modern economics, Scotland’s greatest gift to the world was its national sport, which is the greatest game ever invented.
Haggis is a luxury???????
