Sounds like a tricky question.
I would say that if my partner would basically do everything for me in housework I would feel uncomfortable if I was not also on some level giving back to the relationship. Not that I like traditional roles but I feel in those there was at least the assumption that both work, one at home and one for another boss.
In a scenario where someone really just does everything for you and there is nothing to contribute that would also feel grating and uncomfortable to me. Just hearing about a partner who would cozy you up for a while though sounds chill to me and something that has happened to me and I have enjoyed. Especially if it feels contextually appropriate: you having a rough patch and getting more support from them.
So when I first read it, thinking about my partner and me just chilling and me not having to do much of anything that did sound slightly tempting on some level as a fantasy.
Maybe that helps as a different perspective?
I mean, I get that you don’t like how they talk on Lemmy about it, but the quote from the study even talks about how the surplus could be used for additional consumption and everything. Study is here
I think we all have different things we want in life and with such a big surplus there is room for most of us to regularly enjoy that. I do not believe that they argue that we will NEVER be able to enjoy different food. That is as you have mentioned not functional or good for people to work together and live together. Disregarding the many people with different cultures that have moved somewhere else.
I think the study more clearly argues that we can afford to take care of everyone on the world if we wanted to. That there is a viable way and that that way is not as you are implying necessarily a deprived space with tight margins. Because living is about more than slaving away like a 12th century peasant to accumulate more wealth for a king somewhere far off.
