In a communist society, where everything is free, continuing to experience luxury primarily through material possessions is not feasible (due to limited resources) and not sustainable (due to environmental impact).
Luxury through material possessions can be part of it, but our desires for luxury will have to be primarily oriented in other ways.
What other ways? I made a list which covers a lot but would like others to add to it. Will likely put this in a video one day, so I want to make the list nice and thorough.
> Luxury through abundance of free time. In a society where work is voluntary, all time is free, to spend as you choose.
> Luxury through satisfying productive activity. Cue Marx quote where he talks about how in communism, where people are free to do whatever type of productive activity they choose (so long as they're qualified/competent), labor can become one of the primary ways we satisfy ourselves.
> Luxury through friendship, socializing. More time for this.
> Luxury through beautiful, clean environments in our neighborhoods and cities. Imagine being constantly surrounded by beauty, art, trees, gardens, beautiful homes and buildings.
> Luxury through access to all sorts of recreation, arts, and cultural experiences.
> Luxury through the joy of learning, of creativity.
> Luxury of being free of any form of money stress, free of worries about losing what you have, of getting sick and no longer being able to afford your home, of not having enough to make it through old age.
Other ideas? Or can you expand on any of the ideas I already mentioned?
If you've not already, I would strongly recommend reading Communal Luxury by Kristin Ross (sure there's free PDFs around somewhere if you want). He's covered in the Luxury book, but William Morris is also worth looking at here, I think.
