If you're able to do better than that, then you are in an uncommon bracket.
To be fair, I personally am on an uncommon bracket where I usually socialise over the internet, people who make games tend to like playing them too, and there is no commute.
That said, you're still framing it as a work thing. Your peers can do whatever they want, but the rest of the world still exists. Unless you're saying everyone within 20min of your commute path also follow this routine pattern, but then I would expect you to be on an uncommon bracket.
There are countless activities you can partake that involve interacting with other people and give you opportunity to create friends.
Leave work at 5 (hopefully!). Gym/exercise for an hour, commute for 30min, dinner for an hour. That's already 7:30pm. Add in chores or errands or distractions or whatever and 8pm comes quick.
Like yeah, I could start doing microwave dinners or not exercising or replace all my food with Huel like someone actually suggested in the comments here. Or move right next to the office or leave work early. But my god I'm not going to hyper optimize my life in order to maybe see people late on a weekday.
My whole point in this entire thread is that I socialize during work. At lunch, during breaks, between meetings, etc. Time I would have not been working anyway (because I'm not a robot). This is what people have been doing forever just fine.
Even with 4 hours of chores a day, that's still 4 hours to do whatever you want. Doesn't mean you spend them all that day, or all of them socializing. Maybe you use mondays to study, tuesdays you spend more time cleaning so wednesdays you can go out do something.
Also consider that if you strictly socialise in a work context, most of those relationships will grow distant relatively quickly when you or they leave for another company, which means it's harder to build long lasting friendships. Those can be really handy at times of transition in your life, which is where work friends usually fail first.
