Homeschooling typically involves very little sitting at home, doing traditional schoolwork. As others have noted, and my extended family's experience supports, it only takes maybe 4 hours max to get through the basic curriculum--usually less--when all the ceremony of public school is removed. That frees up a ton of time for a combination of self-directed learning, engagement in extracurricular activities with other children of a variety of ages (e.g., may nephews have done karate for probably ten years now, started learning with older students and progressed to helping teach younger students) and regular "field trips" (e.g., when there isn't a lockdown in effect, my kids go to the aquarium at least once a month, and interact with the... zookeepers? fishkeepers?... there to ask questions about the animals, pet the rays, etc.), and navigating the world with their parents. Now, a parent can still isolate their kid from responsibility, by, e.g., taking them along on an errand to the bank and the grocery store and making them be quiet and Let The Adults Talk, but they don't have to, and those who choose to homeschool generally don't. Heck, my kids aren't even school-age yet, but I still let them hold the credit card, talk to cashier, stick the card in the chip reader, take it back out when it beeps, and grab the receipt. And since they are around the house with their parents, they also tend to get to know many of their parents friends, which is conducive to learning how to interact with adults, who are not your teachers, socially. On top of all that, even when engaging in core curricular study, homeschool kids are usually doing so in mixed-age groups, according to subject ability level--especially if they are part of a co-op.
