For example for some one where anxiety acts in a way which hinders him to proper handle thinks like making food or cleaning having a clean office with a Mensa giving out reasonable good food for a reasonable price is a massive difference. It can make the difference between overcoming it and complexity succumbing to it to a degree where you at some point end up homeless on the streets....

Sure just one example. But you can make many such examples. Often less extreme.

But however I look at it it always boils down to people being good of (housing, mental health, social net and high sallery (==more affordable office equipment)) profiting from it but people which are not (small dark apartment, mental health problems, abusive partners, social isolation, not much money) paying the price for it. And sure in the praxis you will find anything in-between.

> allready have a dedicated office in an exurban house

In my experience (Germany/Berlin) this normally only applies for people which earn above average and even then it not so common for people only earning slightly above average. The best/most common thing you find with people earning slightly above average is a room which is intended for children but they either don't yet have any or they already moved out so it was turned into a office room.

Also most office at home room I have seen where just suitable for one person, so if both partner need to do home offices it gets space-wise tight.
