As the default, we all have a little experience in it.
There is a need to defend it though. I've already seen several businesses claim that remote work is "the future". Personally, I feel that remote work has been very detrimental to my mental health and I hate it. I don't want that future. It feels very unhealthy.
Is it possible that these two circumstances are overlapping in your case?
Do you miss the commute and sitting in an office (on-location work) or do you miss speaking with people (socialization)?
I mis-conversations being unscheduled
And I miss socialize "with coworkers". We're working on the same project. That socializing helps know what's going one, what each other is doing, what problems we are running into. It gives up empathy for each other tasks etc. Reading about it in various forms of online databases doesn't come close.
I miss having lunch with coworkers the most. There's some natural bonding and trust building that happened over lunch, talking about random things, both work and not work related. This is very hard and possibly impossible to replicate with remote work.
With remote work, meetings are scheduled for a reason. Meeting just to "hang out" feels weird. Multi-user meetings with more than a few people also feel off because everyone is interrupting each other, you can't have multiple threads of conversation. Talking on slack, you usually can't tell how the person is feeling. The tone is lost. I've found communication is generally much poorer.
No thanks for offices.
I'm back to the office most days of the week although I don't have to. Big difference being that there are no longer implicit or explicit expectations what hours of the day one is there, I can just stay at home to work on something or wait for a delivery, due to only a part of staff being there any given day it is more spacious and pretty much as quiet as at home, etc.
I actually have a separate room in my apartment I could convert into an office, but I don't want to, since I would have zero use for it outside work hours and prefer to use it for things I actually want to do at home. Sure I could move out of the big, expensive city into a more spacious home, but then I wouldn't live where I want to live.
I don't think there needs or should be a default, and I don't want to go back. Companies should just choose whatever model of working they prefer and see what talent they can attract. Maybe in person work becomes niche. That's fine for me. But i'm honestly getting a bit tired of the "why would you want to socialize with co-workers, don't you have real friends?", you now often get if you mention you personally favor a hybrid model.
Collectively we should work on this first before jumping the conclusion "all juniors lose out on remote" or smt. Remote gives you a lot more freedom and telling juniors that it isnt for them is kind of gatekeeping.
Internet forums like HN will always overrepresent preferences for remote work because they're biased toward people who enjoy socializing over the internet. Most people don't go online and engage in random discussions. They do it in person, and they like it that way. A random sampling of active HN commenters is going to be much more enthusiastic about remote work than, say, your average junior who relies heavily on organic interactions to grow in an organization.
