That's a completely incorrect mischaracterisation of the analogy.
I'm not talking about replacing a block of time with nothing, people will still have 24 hours in the day. My worry is about replacing income with nothing, because most people don't have the power to seize any income that isn't freely available.
The public takes what they're offered and can't have anything that isn't on offer. If the offer of access to food is withdrawn, the public has no recourse.
Right lack of income has to be dealt with UBI, or worse handouts from big companies. Why do big companies hand out? Well... we get to a point where that is ther smarter thing to do than lose consumers altogether. The incentive to be rich is to have your ideas forfilled rather than to own a home and have security (as that can be provided for all).
If you think this is madness, the analogy (yes another) is you are playing uno with people you met. They have no money. You can say well never mind we wont play. Or you can just deal the cards because they are so cheap it costs you nothing just to do that. And that is more fun. This is what post scarcity could look like.
It's kind of like at the beginning of the COVID-19 pandemic when some in the US were saying that the US government should just forgive mortgage payments so the landlords could forgive everyone's rent. Instead the US government gave businesses loans so they could pay their employees (even though they weren't able to work) so those employees could then pay their rent and buy food, etc. It was (perceived to be) better to inject the money into the system to keep the current system running, rather than turn off / forgive the major parts of the system.
Under the K-shaped economy it's been reported extensively already that the consumption market share of the public is trending downwards with no side of stopping. The consumption numbers can be kept up entirely off a market adjustment for less food and water and more yachts.
Post-scarcity requires a political choice. Everybody with political power, regardless of affiliation or nation, stands to benefit from reducing the political power of others who may stand to make demands. The economically surplus humans can't make those demands upon the powerful if they aren't around.
As an analogy imagine you had a 6 hour driving commute each day (3 each way)
Imagine if now you move next to the office.
Will it be bad you get those 6 hours back?
If 15->9 is good then 9->0 is even better!
The problem is adjusting to that at scale. Will we get addicts or people who never leave the home? Maybe.
