Counterpoint from my own experience having been previously homeschooled all the way to college: My parents went the extra mile to ensure I was constantly immersed in large group settings with other homeschoolers. Field trips, co-op classes, sports, and general high-quality social time. There were of course bad eggs as in any group setting, but with an important difference: if it ever got bad, it was possible to leave, and we did on occasion. In my mind, that's far more in keeping with the "real world" than the seeming entrapment of public schooling that offers little recourse for when social experiences sour. In the real world, you have the freedom to leave a toxic job or social group far more so than public school.

In addition to peer socialization and mobility, the flexibility in scheduling allowed me to work a day job through my high school years, exposing me to yet more real-world experience. The constant interaction with adults and folks from other walks of life was a huge boon that allowed me to function as a well-adjusted adult right out of the gate. The high-school drama that people suffer and then bring with them into adulthood is very disappointing and seemingly unnecessary.

^^^ That's my experience interacting with healthily homeschooled children-now-adults. On average they seemed to have so much less trauma than me and my peers, and less "subconscious" issues to deal as adults.
