What UBI enables, I believe (and same with universal healthcare and other social safety nets) is lowest barriers to entry. I have no doubt that some will not do anything productive with the moneys it’s pretty much beside the point.
The point is to have a guaranteed floor for all in society, much like the idea of bankruptcy (before the conservative demonization of the idea particularly in the 1990s and Bush era, in the USA) it’s a way to ensure people can start over or continue to build momentum without fear of being homeless, starving and/or being unable to provide the basics for their family or themselves
This lowers the barrier of entry for people to free themselves of being shackled to giant corporations or dead end jobs just for “security”
