Working alone at home would be a worse option for me than working in an unfavorable office environment. More like a non-starter than worse. I get that there are people who love the idea of being isolated. But I think there are more who want to be around people instead of alone. And there should be a reasonable option for them, not open plan.
Remote does not mean isolated. I spend most nights and weekends out with friends and groups. When I worked in an office I would frequently be too tired from interacting with people to plan things.
