>I’ve also read translated classics from my mother tongues and I know how woefully inadequate they feel.
This is an interesting point where our experiences totally differ. I have myself read a few classics in both original and translation, between the English-Latin-Spanish triumvirate, such as Cien Años de Soledad as you mentioned. I percieved little if any drop in quality between Marquez and the translation - indeed I often thought the translated work was superior to the original. It's not a classic in the same vein, but I similarly found the modern Latin translations of Harry Potter were much more fun than the original English prose, which even as a kid felt very workaday and even uninspired at times to me.
So I see this more as evidence that you put a very high aesthetic value on linguistic purism than anything else. You don't just want the thing, you like working really hard to get the original thing. You like pushing the boulder up that hill. To be clear, I consider that an extremely commendable character trait, I just also think it means you're living on another planet compared to most of the population. Which isn't a bad thing, it's nice here.
>I don’t need to sacrifice anything that way.
It may be a sacrifice you're happy to make, but you are absolutely making some kind of large tradeoff every time you invest 500-1500 hours into learning a new language to C1 level, man. Like come on. That's like the economic definition of an opportunity cost.
