I hope I can go some way to towards answering your question. I take your point about the illogical basis for UBI. You're right to question where the money can possibly come from. However, I think UBI is part of the future being planned for us all. The commodity of the future will be data and carbon. Instead of being taxed, in the traditional sense, we will be farmed.

The data we create will have value and will be traded. Therefore each of us will generate income for those involved in that trade. The role out of the 'internet of things' will create huge volumes of 'energy usage' data for each and every one of us and, through creating a carbon trading market, that energy usage can both be rationed and moneytised. The profits made from the control of energy and resources will provide sufficient income streams for global corporations for them to fund a subsistence income for the masses and facilitate their control of everything we need to exist, such as housing, food and water. This concept is laid out fairly clearly in the U.N's Agenda 2030 document. Essentially its government by global technocracy.

The thing to get your head around here is that the sale of goods won't necessarily be part of the new technocracy. The necessities of life will be controlled and provided, rather than earned. Earning will cease to have meaning. Indeed aspiration, in terms of commercial activity, will be destroyed and replaced with centrally controlled supply for those who obey the rules. Loyalty to the technocracy will be rewarded. Independent entrepreneurship will become obsolete.

We are all anticipating the loss of at least 47% of all jobs in the next decade. As mechanisation destroyed many manufacturing jobs so A.I will irradicate service and white collar jobs. Therefore we are having a technocratic control grid created to ensure our existence generates income for the globalist corporate elite.

As for dickturpin's comment about Nationalisation by the so called Labour Party I wouldn't worry about that too much. It seems to me that they fully intend for us to remain in the EU (mind you, so do the Tories) so there won't be any possible nationalisation when we do. EU regulations forbid it.

Here is an interesting vido if you are interested in what I'm talking about.

Great post. Upvoted and resteemed.
