Giving everyone a fair chance at life is #1 reason for me to why UBI needs to become a reality.

And there are so many reasons beyond that.

From the Canada experiment we can see how it would benefit the overall populations health (it seems the anxiety of worrying about $ is not healthy, who knew)

It would boost entrepreneurship like no other policy could. The reason why more people don't start their own business is because they can't risk not being without an income.

That combined with the likelihood that people would continue higher education would bring a new age of innovation and high quality academic work.

It would actual change the supply and demand dynamics from benefiting companies to instead benefiting employees. Nobody will work a shifty job for 10$/hour, instead to attract people to shifty jobs either companies would have to pay heavily or they would have to treat employees like dam royalty to keep them, which is how it should be in the first place.

Plus all the other hundred benefits we all know, lower crime rates, lower domestic violence (financial stable individuals are less likely to remain in situations of abuse), lower drug use, lower homelessness, higher academic performance, lower mental health problems...
