Not out of the question. But not every native Spanish speaker knows how to teach it.

They don't have to know how to teach it, they just have to be better than the public schools at teaching it. Having taken Spanish in High School, I can assure you this is a very low bar.

And the point about things like music classes still stands. A Zoom music lesson is no substitute for an ensemble experience, not even close. How are you going to do lab experiments this way? Like things where you're working in teams? I know that...

...homeschoolers do it, but they also generally have the luxury of at least one stay at home for work from home parent.

Wait, you're conceding that homeschooling can work but microschooling can't? For what it's worth, I spent years on Spanish and clarinet in school; today I can't speak the former and can't play the latter, but wouldn't need to go back to high school to pick up either again.

Everyone's mileage may vary. One of my kids is only taking French because they have to, the other one is up to sixth year French and is hoping for a job that will use their French language skill. My bass player is not going to forget how to play bass.

And yes, my bass player possibly could have learned via YouTube and did learn via a private teacher for a while, but again, the large ensemble experience is similar in nature to foreign language immersion.

But simply conversing in another language does not necessarily guarantee any fluency either, at least not beyond the bare essentials. Witness difficulties faced by ESOL kids even after several years of immersion. Not the same as explicit instruction which still has shortcomings.
