> What under UBI is preventing me from quitting my job and spending the rest of my life playing videogames?
Nothing, except that UBI is a basic income, so you don't have the money for the latest and greatest gaming PC. You have enough money to not go homeless, but not a whole lot more. If you want that PC, you have to still work for it.
If you look around, most people aren't exactly living the most basic life possible with the least work possible, they quite like their luxury goods in exchange for work.
That depends on what is the definition of basic. I assume food, electricity, water and a place to live would be covered under UBI, I think there's no arguing about that. But anything else? I can easily imagine calls for extension for things like entertainment. Should internet access be considered basic? How about TV or a game console? Mobile phone? I'd say these shouldn't fall under "basic" needs, but that might change.
Not everyone has the latest and greatest gaming PC; I know people that can afford it, but they play games that are 2-5 years old they can buy discounted ($20 instead of launch price of $60) and the average computer of the day can play with max settings. Living on UBI does not make people stupid, just lower budgeted and even encourages making some better decisions - having more sense than money.
