Consider carefully and closely what those social aspects are. Check that your perception matches reality. For example, in the classroom, 90+% of the time students are supposed to be quiet, or to interact with the teacher (usually answering a question—in front of, but not with, the other students). Most of the social part of school is interacting with friends at recess and lunch, and sports and non-class activities.
Furthermore, the parts of school that are social are not necessarily good: for some people, they consist of being rejected or even bullied, and making them suffer that for years may lead to socially avoidant habits, anxiety, or other long-term issues.
As eloff suggests, sports and other activities are a good way to get good socialization. Since the activity is voluntary, all the kids can be expected to share at least one interest with your kid. Also, if your kid meets some people he likes, then what are called "play dates" (at young ages) or "hanging out" (at older ages) can lead to deep, long-term friendships.
I left high school at the end of tenth grade, but continued going to the math club and attending an after-school math contest class, and hanging around in the math department's common room with others who had a free period before that class. The school was happy to allow it because I was good at the contests, and it made the school look better to let me participate. I got about as much socialization from that as I did when actually attending school, and I was happy with that.
Most definitely - however it's also worth bearing in mind that if you happen to fall into a more traditional life path afterwards, those social elements will rear their heads again.
The sink or swim mentality of school social interactions sadly mimics quite a lot of interactions post school as well. In an ideal world my shitty experience at school wouldn't have been relevant as an adult, but it has actually helped navigate quite a number of toxic situations.
As sad a world as it is, I'm (somewhat perversely) glad I was able to learn how to cope with those as a teen.
It's very common for people who admit that school sucked, to then defend it by saying "it taught me to deal with it". I say, if you really wanted to teach that thing, you could probably come up with something way more safe, time-efficient, and pleasant. I mean, how many weeks would it take for someone to teach a course on "Common personality problems and sources of conflict in the workplace", or something, that would cover 80% of what you learned plus some things you didn't experience? Most of the time, when people claim school is good for a particular thing, you can quickly see that it's nowhere near optimized for that thing.
I'm certainly not defending the way it worked out, but we focus on an idealised education from the perspective of the learner (i.e. curiosity, passion, zest for self improvement), it might not prepare them if they end up in more traditional scenarios. Fully support the notion of it being taught like a traditional subject, just that it's important those lessons don't get lost (which I can foresee happening).
If the light behind your eyes hasn't been diminished by the experiences at school, it's likely it'll be extinguished in less than ideal real-world scenarios. I'd hate to see the joy of someone who genuinely has a zest of learning and curiosity to be crushed the minute they come across the things a lot of us deal with on a daily basis.
Lookup two sigma problem. Kids with a 1 on 1 tutor do two standard deviations better than school. That's an insane advantage if you can find a way to make it work.
Certainly social contact and learning is something you want to encourage, but I would not let that hold you back from homeschooling your son if you feel it's working very well. It's complicated to do in the current situation, but playdates, sports, field trips with other homeschool kids, etc. go a long way. There are likely also co-op classes where your kid can meet other kids.
I'm still friends with dozens of kids I was homeschooled with. Most have had very good outcomes. I don't feel that the few who haven't would have done much, if any, better in a traditional school environment, but that's an educated guess.
Biggest boogeyman ever.
Just make sure he has a few kids he can maitain contact with an be sociable in clubs or in the neighborhood
All the "social aspects" you get from school is basically a bunch of kids you have no controll over, having a disproportionate effect on the moral and emotional growth, or stunting, of your child. And then add all the trauma burntout teachers can generate...
