No plausible UBI system gives people so much money than they can relax and order food delivery while they watch all of their entertainment from their paid subscriptions.
Funding UBI is extremely hard. We would have to more than double our tax intakes to even begin to give a reasonable UBI as a social survival safety net, even if we consider eliminating all other social services.
UBI isn't a life of luxury and food delivery. It's a roof over your head and enough to afford groceries.
It's also confusing that this article thinks the wealthy are going to eliminate all the jobs and then ask to have their taxes raised so the money can be recirculated back to the people to spend on companies. Where do they think the UBI money is going to come from? Or do they believe that UBI is a money faucet that produces new money?
