People have to do what's best for them. If they need to commute to a job to have a social life, let them. This is absolutely not a reason to force other people to do it.

Boomer here, software developer, I started fighting the telecommuting battle with managers in the early 90s. They'd say, "We need you here." I'd ask, "Why? I can dial in. You have contractors in India you've never even met, and that works out fine." "That's different." "How?" They never could come up with valid reasons why we really needed to physically be there, and would generally shut down the conversation with like, "Well, I can see we don't agree on this." Correct, and 30 years later they're still making the same ludicrous arguments.

Yeah my boomer dad (materials scientist in the civilian nuclear sector) disagrees. He's been working from home (and from vacations sometimes...) at least a few days a week for quite a while now, and his old boss was apparently saying that they were going to need to hire 3 people to replace him when he eventually retires.

FWIW I also know some elder millennials who are against it, but I've seen how they run their business and let's just say I wouldn't take advice from them.
