The only problem is really consent and the propaganda against these goals. E.g. Air conditioning or cooking is rather nitpicking, those are not real issues, technological advances and passive house design would easily solve that. With Kite Power you already have unlimited energy.
And you could build a huge apartment block surrounded by nature, growing food directly around you and sharing infrastructure. Everyone could get a luxurious apartment with high ceilings and a killer view for everyone. If drastically less people need to commute to work, we wouldn't need to live in a city. You could also have communal kitchens or diners or cafeteria.
The greatest luxury of all would be to have free time. To enjoy life, to study and learn for free, to raise your children in peace. Not consumerism. Let the masses produce VR games if they have too much free time.
I also disagree that it requires full on communism, a UBI or expanded bill of rights for the human necessities to reach a decent living standard (DLS) could work too. You'd just heavily regulate, ban industrial meat production, bad advertising to avoid consumerism etc.
