A healthy friendship outside the workplace is maybe 25 hours per month of contact, at the upper end. That's meeting frequently for meals and spending 25-50% of weekends together. If you manage to have 3 of those, that's 75 hours a month of being around other people. Still quite far from the 160 built into an office job.

I don't think friendship is a substitute for the socialization an office provides. A roommate situation might be, but that has other serious challenges.
