I'm with you on general principle, but the two physical parts of civilized society are markets(trade) and consumption of resources. Managing civilized people for better or worse comes down to managing the information about the trade and perception of resource availability (payment, ownership, where tomorrow's meals will come from). In modern markets, people are massively manipulated by prices and wages to compete for things they mostly shouldn't need to buy (cars, clothes, petroleum products, entertainment, advertising). Basic needs that can be provided cheaply through technology (food, communication) are turned against the perceived value of people producing for themselves(if you can buy cheap carbs, why grow vegetables?), and material ownership of houses is pushed up in complexity to harvest the cash made available through cheap food. The masses are tricked to borrow more than they can afford in order to keep up with inflation that allows rich borrowers to pay back loans using deflated dollars collected through inflated rents.
No, UBI itself isn't an answer: it has to come from first putting all overhead of civilization into sales tax and eliminating all of the corruption that "love of money" has been using to deceive consumers with "always low prices" and "job creation". The one natural right of living things is the Right to Try to live. It's not a guarantee. Society tries to make itself a conduit from God that provides Life and also takes it away when people don't participate in society's wants. Capitalist society demands that people create money or die. Fanatical capitalism then demands that people make more people who will make more money ad infinitum. This is why the critical part is sales tax. Complex technical society will always be a market based system, whether distributed or centralized, because a market distills needs vs wants down to the price vs labor value. Sales tax that includes all externalities becomes an information conduit going two ways; from leadership to citizens and from citizens to government(by choosing to make instead of buy). UBI then becomes the price society itself pays for existence (and cannon fodder).
Capitalists have kept demand high for their rhetoric and corruption simply by creating the illusion that assholery(blind competition) is faster and cheaper than any alternative. Anticapitalists think that the opposite of extractive capitalism is extractive socialism rather than sales tax and reduced demand as well as reduced competitiveness(UBI's greatest value) overall.
UBI (including good health and educated citizens) is not a solution to capitalism: it's a measure of the health of society.
If the UBI (overall gain of each citizen and the quality of places) is growing, then a society is working. If only the moneypot is growing (GDP), then society is useless to its places and people; serving only numbers on spreadsheets. The focus in the former is on keeping value close to real places, whereas the focus in monetary theory (inflationary future extraction) is always on imagined places )Mars, stock prices, growth, interest, dividends, demand). Sales tax is the anti-imagination factor that humans need to have visible at their decision point. UBI tells them they are worth something to a place and each other.
