I'm one of those weirdos whom actually prefers being in the office the majority of the time. Doesn't matter if my colleagues are there or not (this varies) but it puts me in a better headspace and it actually feels like work. I do not get that at home and I am definitely less productive or settled. I am also usually too busy to do my chores at lunchtime and so on.
If my employer went fully remote, at the very least I'd have to look into some kind of office space outside of the home. Most of the happy WFHers I know all have a big comfortable house, partners and families, pets, etc. but I don't.
