I don't disagree. But your assumption is that you would have less social interaction WFH is wrong (at least in my case).
My current commute is 2.5 hours a day. WFH would give me an additional time to do different activities each day (most with other people). Currently I'm limited because my preferred activities, I won't get home till close to midnight.
Having that commute time cut to zero would allow me to pursue my interests and have more social interaction than I currently do going into the office each day.
When I worked from home I lived in a difficult climate which became overly pleasant. The worst snow storm didn't bother me in the slightest, if I didn't feel like going outside I just didn't. When bearing the cold became optional, it was a pleasant luxury going outside instead of a chore.
The human interaction you are talking about is real, but so is losing a large chunk of your life getting to work.
There are other realities to contend with, like how it looks bad to have a six month job on a resume, or leases that are expensive to break, or how moving when your lease ends to somewhere better to commute to a job you've lost confidence in, or waiting for a vesting cliff and promised raise, or moving far enough away that your friends might as well be in another state...
Not to mention if you have a family or partner.
In the long commute case, much of that was true. I tried to stick it through hard times after they moved offices to be significantly further away and burned out. It happens.
Life isn't always so simple and you can't always optimize your life around your job.
On that note, I don't know if there's any research to it, but I feel like commute is an exponentially increasing nuisance. To illustrate: Moving from a 15 minutes commute to a 20 minutes commute will bring me less irritation than moving from a 55 minutes -> 60 minutes commute.
Half a year plus of a remote work now - I'd argue I have a healthier social life now compared to before when working at an office. I actually have energy after work to go out for dinners and meetups and develop/maintain the personal connections I couldn't before.
That's what one has a family and friends for, not necessarily work colleagues.
