Let me present my counter-tale to all the anti-home school comments.
My kid is autistic and the schools are some of the most poorly funded in the country. Despite this the school did an excellent job and had very good staff that did a very good job. But as my child went up in grades the resources available decreased. It was quickly heading for a point where the 1-on-1 time they would need wouldn't be available. Then the pandemic hit. We were forced into online school when the school closed for a bit. The amount of specialist time available dropped to near-zero.
The school wasn't prepared for online school and the sites/curriculum they used were all over the place. We supplemented with our own field trips and additional resources. But they otherwise took to it really well and were still learning.
The next school year our school still didn't have its act together. We found a different online school that actually had good curriculum. They've been going to that ever since and it's gone really well.
BIG CAVEATS: I used to be a public school teacher. My degrees are in that, and I was certified. I work in a different field now, but I still have that background to know adolescent psychology, how to evaluate curriculum, knowledge of what is grade-level appropriate, etc. My partner specialized in language and writing, while I was science, math, and tech. We take great pains to socialize our child with outside activities, and make sure they read and participate in art/creative activities. My partner is stay-at-home with the primary job of seeing to our child's education. I help but assist in my areas of expertise.
TLDR; Home school IS used as a way for a lot of parents to enable hyper-religious or abusive behavior, but that's not universal. In some cases it can be the best solution for the child.
I would say it is largely impacted by available resources, but not necessarily limited to government. Some locations have great non-profit organizations dedicated to exactly this sort of thing. I'd say a lot of places have those sorts of resources, but often are hard to find.
