Given that English in its earliest intelligible form is a merger between Old English and Norman French, I'm not really sure what English with loan words removed would sound like. Probably like Beowulf, and I'm sure I couldn't understand it.
English is a great language (though a very hard one to learn) precisely because it's cobbled together from bits of other languages. If another language has a word for a concept we're missing then we just acquire the word.
So if your friend gets drunk on tequila and vodka and eats too much foie gras and winds up with a tattoo of a voodooshaman holding a katana in a sauna dancing the hula with a walrus then by all means you can feel schadenfreude about it.
Which is all very well until you're playing Scrabble and your letters spell all sorts of pronouncable wordshaped sequences which you are sure must mean something to someone... but then they aren't allowed. :-/
