They see universal free money as a cushion for workers whose jobs might be replaced by automation or robots.

They argue that free money could provide workers with the flexibility to retrain for a new career, pursue creative interests, or start their own business.

If we are talking about a temporary benefit during a retraining period, then that is an entirely different idea from a universal basic income guarantee. You can drive down the streets in New Jersey and you see hand-made signs posted that they pay cash for diabetes medical material handed out free by the government. They also sell food stamps. You cannot change humanity. Some people will obey the rules and others will circumvent them.

The last thing you want to do in society is provide to the population some sort of guaranteed income where people can stay home and do nothing.
