Do you want to live in a land of garbage? If no one wanted to pick up garbage at the current wage being paid, there are options:
a) offer more for the wages
b) reorganize trash collection, such as neighborhood dumpsters or taking the trash oneself to somewhere, possibly reducing the amount we all use
c) communities deciding to get together to clean up their own neighborhoods.
This is a bit like shoveling snow. I shovel the street around where I live so I can park there. Some people help, others don't. I'm fine with that. I care about it being shoveled so I take action. If I didn't care, then I wouldn't. That's the point.
Fundamentally, playing video games and watching videos gets boring after awhile. People want to be useful once their survival and security needs are met. It is obscured in our society because low wage workers are barely surviving and the bs jobs people, who often make plenty of money, do not have long term security. They know that they can be fired at any moment because they are not actually useful. That job insecurity is what fuels the managerial feudalism and why useful workers are squeezed out (they have the true power to strike).
Much of the population lives below the point where the drive to be valuable kicks in. Implementing a UBI would allow us to potentially get above that point.
No one wants society to fall apart and so it does not. If everything was based solely on money, there would be no kids, there would be no helpful people, there would be no taking care of elderly parents, there would be far more law breaking than there is, etc. Society works because we need it to do so and we will do whatever it takes make this happen.
