Why does that matter?

It's honestly absurd to make the case that you don't have time to learn the language of a country you're spending 100% of your day in.

What are you doing all day? The people who are struggling to learn a language tend to be the people who have zero pressure to learn a language.

The most time consuming part of language learning is immersion, meaning that you just listen to or speak the language, without going out of your way to do any language lessons at all.

How many languages have ypu learned with your immersion technique? Maybe you should search a bit of research on how successfull your immersion is for adults learning a new langauge. Perhaps then take a look what research says people who actually learn new languages (not youtube polyglots, people who have to do it for work etc.) do.
