Basic income is always seen as a way to freedom.
That is true in today’s world, were people are still forced to take jobs to survive or live of welfare scraps, otherwise they’ll end up on the streets. A basic income would better that situation. If the government decides to end UBI, the world would just revert to the previous state and we wouldn’t loose something we didn’t have before.
But if machines do most work and the government gives everyone basic income, because there would be no other choice and imagine if over half the population lives off the UBI only, it would give the government massive power because it would control the income of the majority of the population, so most people are dependant on it. If UBI get’s cancelled for whatever reason, they’ll die because they couldn’t just get a job again, since there’d be no more jobs.
Now imagine, the government does shit and people start demonstrations. They’ll just shut off every rioter’s UBI. See how soon protests cease… The gov could also use it to pacifiy the population, like “hey, we’re going to start useless wars, take away freedom and imprison innocent people, here, have a 20% basic income rise”.
Though, all of this assumes that UBI is going to be payed by the government and not by someone and somehow else…
