I don't doubt the kids can get a quality education at home, however my years in school involved interacting with many different people both older and younger, teachers who shared their life experience and simply dealing with things like conflict resolution, following directions, time management and so many life lessons that have helped me in my adult life. Many of my lifelong friends were cultivated through my school years. Traveling to sporting events, pep rallies, proms ect, were some of the most memorable times of my life. I would hate to deny my kids those great times. I think sheltering kids from the outside world will hurt them in the long run, think what the Dugger kids will go through when they have to get a real job and mom and dad are not there to tell them what to think and do, just my thoughts, I respect any parent that has that kind of dedication to their kids, I couldn't do it
You don't have to deny your kids these things to homeschool! We brought DD14 home in 6th grade intending to return her to the public system in high school actually for lots of the reasons you stated that I bolded. She is having so much fun that she has asked to stay home though graduation.
First, we live at the intersection of 3 school districts, so her best friends didn't go to her school. She had friends at school, but her best friends, the ones she invited for sleep-overs and wanted to hang out with, did not go to our system. So her interaction with them did not change at all when she became homeschooled.
Second, our homeschool group is very large (about 750 kids). They have a LOT of social stuff for high school-aged kids. She is in Key Club, band, yearbook staff, and she takes English and Spanish at our co-op (a teacher, in a classroom setting). I don't know jack about Spanish and didn't feel competent to teach her. I am good with English, but we were butting heads over it. She is happier now learning it from someone else. I teach her science, history, and math. DH was a math minor in college (went through Calculus 4) and I used to teach college, so I have no qualms about the quality of her education.
DD *loves* football games and we were at nearly every game this past fall. You don't have to attend the public school to go to the games. She had lots of fun seeing her friends there, just like any kid. She also has many friends now in our homeschooling group. She's going to Key Club state convention this month. Most of the kids there will be from public schools.
We have fall and spring dances. In fact, I just bought her prom dress for this year. Just gotta get the shoes.
As an aside, I went to public school and didn't really care for football, so I found pep rallies boring and I rarely went to the games (don't know where DD gets her football gene - even DH doen't really like it! LOL) and I never went to a dance. Back then, girls didn't go with friends like they do now. If a boy didn't ask you, it was just too bad. And I was slightly overweight and a straight-A student, which meant no boy was ever going to ask me.

So these experiences we expect kids to have at public schools aren't true for everyone.
Oh, I almost forgot! Homeschooled kids do very well at learning time management and such, and most do very well in college as they are already used to being self-motivated and managing their assignments through the week. I never help DD with Spanish, and rarely help her with English. (I might proof an essay or help her understand Shakespear - they're reading The Merchant of Venice right now, and she finds the vocabulary challenging) but she is solely responsbile for getting her assignments done through the week. These classes meet one day a week. She learned very quickly it was a BAD idea to wait until the night before to try to do a week's worth of work. Some kids don't figure this out until college. My niece and nephew were both homeschooled K-12, and are doing fantastic in college.
DD12 also came home in 6th grade (our middle school is abysmal!!!) but all of her friends did go to her school and she misses seeing them during the day. She is also a very different peersonality than her sister. She is still saying she wants to go back in 9th grade and we will probably let her. Our main reason for homeschooling was so our kids would get an education. The high school is okay for that, the elementary school was excellent. The middle school...not happening.
When DD14 was nearing the end of 5th grade, we actually had someone tell DH *to his face* that they had nothing to offer DD at the middle school and where did we plan to send her instead.

This was a school employee. They suggested a couple of private schools that would be great if we ever win the lottery - lol. (tuition $12K for middle school there

) DH was on the fence about homeschooling, fearing the children would miss out on stuff, but that pushed him over the edge.
DD14 does something out of the house every day. She has band, she volunteers at the Children's Hospital, she takes ballet, tap, jazz, hip hop, and ballroom dance (at a studio with public schooled kids) and she also teaches a beginning ballroom dance class, she rides horses, plays piano and flute, and babysits two days a week. Plus the Key Club, Yearbook, and our church youth group activities. She wouldn't have time for all that if she had to spend 7 hours at school every day!

She takes more subjects at home than she could take in school, too. At public school she would only have 6 classes, but at home she has 9. DD12 has 10. (In addition to the required English, Math, history, and science, plus PE, I teach them geography, keyboarding, a foreign language, Bible, and art/art history).
Yes, it takes a lot of my time, but I *love* having my kids home and being with them so much.
