Of course, 2str, 2*str and str*2 could be equivalent, as they are for other data types. For me two (copies of) str is just more natural than str1 times str2. Similarly, "add" str2 to str1 for concatenation follows the natural language better. Also, you could define str1-str2 as deleting str2 from (the beginning/end of) str1, if it was there. (even though str2/str1 works, too). You can find in algebra ample examples for both multiplicative and additive notations for structures, but either way the notation of string concatenation is the least of our difficulties when learning Julia.
