Why would universal income work? Why wouldnt it?

I've been pondering on this questions and I don't seem to get an answer that I like in any way. Let me start by saying that I do not intent here to make a technical analysis out of anything. I just need to start a conversation around the questions that I can't understand.

First there was time

I get that we are not good handling time. It is not an easy task to take and, it has not been that long since we started needing dealing with it. Time, is what we use in order to survive. If we want to get to the next one, every month we need to spend our time in at least to things. Getting things to ingest, and burning stuff. So when modern society takes a providing role in both instances we end up with the glory of our day Leisure time

I don't think we are ready to have only time that is not needed to do something. But regardless of haw I feel about it, automatization and technology are taking any task we used to spend time in, and are doing it for free or almost free.

So what are we going to do when there are no mandatory actions anymore. Leisure management is, I have no doubt about it, the profession of the future.

Money and why we exchange it

I try hard not to be simplistic about this. There are two cornerstones, modern cornerstones I mean, to understand money. The first is Piketty's book, in which we can learn about the current state of affairs, and worry about the future . The second one is the book from Graeber where he explains money from a human history point of view and not an intelectual exercise.
What I think we need to do is start thinking about the why of this exchange. Power and money go together. Property and money go together. But exchange does not seem to be that broad anymore. You need a way to exchange value with a guitar player giving a show. But you don't need to exchange any value with an automated bus that runs on renewable energy and self repairs. It just doesn't make any sense to machines to do that.

So once most of the things we have to exchange value for are run by machines, why would you need money in any way? Human coordination, artistic expression and leisure management are the remaining tasks worth paying for. How are we justifying universal income then?

Up goes the bar

Timing is the player here. If a move like Universal Income (UI) comes too early, we will only have a new zero. If money is still in place, having more money on the streets seems to be something we know how it works.
I mean, universal income does not solve anything for those who have nothing. Those people need to solve their burning/ingesting problem every day, or they die, or their children die. Moving the bar up, making more money available is the same as situation they have today. Just a little higher in inflation, maybe, but thats it.
For the rest of the community it is a similar:

• For those who have little it makes no difference, because the bar goes up.
• For those who have some, it does not make a dent, and the bar goes up.
• For those who have plenty, it enables them to rise de bar.
  So I ask again. Why do we use money.

If UI comes when money is not around, then you have another picture. If we could provide a tool instead of expendable resource, then you can make an impact. Once we have no money in place, universal income comes as a tool for exchanging a value that is otherwise difficult to keep track of.

Then there was time

We will exchange value as humans. It is what we do. If money is a measure for everything, then we end up exchanging money. When almost everything we can use it on is free, or, even better, does not cost money, then money goes away.
Once that happens, it is a difficult picture to paint, there is room for a tool. But only in time we can make it work. The funny part is that soon enough, how to invest your time (AKA that thing we can't store and you can't spend a scrap more than you have) will be a financial decision we'll need to take care as a society. The opportunity for UI opens there.
