Then you have a limited cross section of people that you talk to, and it seems they come from a mono culture.
From the people I talked to it is mixed with the majority wanting no more than 3 days, with most going for 2 days at home the rest in the office. The Hybrid model...
The amount of decisions, and knowledge that is passed around in a given office with just idle in person chats in the hallways or inpromptu meetings pretty large in many organizations, this everyday knowledge transfer does not happen in WFH, or happens less often, this can lead to things being missed, people being left out of the loop, etc.
Also it really depends on if a person a location in their home that can dedicate to an Office, that can be door closed off for meetings, and have no / limited interruptions.
I know a few people that do not have a spare room or other space to dedicate to that, so WFH for them is using the Kitchen table, or a desk in the living room that is not ideal... People like this generally prefer to be in the office.
