I don't see what the OPs issue here is nor why they would expect Tesla to pay for this... Components fail, they just do and when it happens to you it's almost always bad luck. Sure on occasion it's due to abuse, but this isn't it, it's just bad luck. OP chose not to buy the extended warranty and is now literally paying the price... A\C compressors failing isn't new, and unfortunately Tesla's right that when they do you often need to replace the entire system due to metal shavings.
For all of the great many things Tesla isn't doing well these days, this ain't one of them...
Also, this is exactly why I lease... Yeah the terms suck with Tesla but at least I know I'll always be under warranty...
