Well, our society needs people who can reason about ethics, for example. We need people who knows history. We need people who can create poetry and art. But capitalist market fear ethics, as it would conflict with profit maximization. It also fears history because it shows that there have been plenty of alternatives to capitalist market. As for poetry and art in general, the greatest artists tend to be poor and misunderstood, and in no way create their masterpiece for the market (that tends to exploit them after their death).
The value of the greatest artists is often really understood decades after their death. So being able to provide value to the society is pretty different from being əble to make society understand and recognise such value.
And the converse is also true: the market pays for all sort of non-sense, that provide no value to the society, From drugs to gamers.
So pursuing only marketable skills as a condition to survival is, again, a way to produce a reserve army if labour to keep wage low.
"Educating the populace" is a better alternative than #UBI if (and only if) the people can earn a living by studying any human field of knowledge. And this does not include weed smoking or any of the strawman you picked, but might include several different fields with very low market demand, such as, say, theorethical phylosophy, history of music, or artic biology or programming in #Oberon or #HolyC.
This because the market do not know what will be valuable for the society.
