Those who wrote the article seem to take offence at people even sharing the same apartment too closely. There was no mention of whether or not the people depicted may be friends or family.
Anyway, my point was that expecting and demanding personal space is indeed a feeling of entitlement. That any normal person deserves it. That observation does not come from my personal philosophies about living, but from what people explicitly tell me. Like when you assert that “Space sharing is not the norm today” but try to make it my problem, rather than people taking responsibility for how they choose to live. If one feels entitled to more personal space, then one will need to use physical or economic force to take it from others. What it does not explain is how/why anybody deserves personal space more than anybody else does. How autonomy factors into this is whether living more closely with others actually prevents you from living as you choose to in any practical way. Or if it more the concept that you (and the writers of the article) are uncomfortable with.
I think it’s funny that you describe my writings there twice as being philosophical, as if that makes them easy to dismiss somehow. Yet the points you brought up to counter mine seemed far more philosophical. Norms, comfort, worries about “an empty life”, chic aesthetics, and value for money are all far less tangible than the practical concerns I was relating.
It also seems bass-ackwards to suggest that efficient use of space is a priority because some people are willing to pay money for it. It is a priority because the geography is a superset of your cultural norms.
