Jess, in reality, it's none of your business what people choose to do in their life. Second, if done properly, there is absolutely nothing wrong with home schooling.
There is also the option of independent study. Which is a program that allows the student to get schoolwork from a licensed teacher, do it at home, and hand the finished work into the teacher in a week or so. It involves due dates etc. So that's another option. I am currently in that program. And I have friends etc. as well. I also manage to keep an A or B avarage.
