That's an understandable solution as well, is this like UBI? or does each person also need to "work" to activate it?

I don't have a formal definition. This post was simply a seed of an idea.

I think it would be essentially like UBI because it is YOUR TIME that it is based upon.

However, if you don't contribute any way then you'll just have your time. To get more time and potentially do more things you need to exchange a service and actually do something.

Who is going to clean a persons house? Grow their food? Fix their plumbing?

You'd have to exchange currency for those services.

If all you do is nothing but collect your currency then so what? That means you end up giving it to others to do the things for you. They in turn then have more to spend how they like.

The thing is there should be no more currency than has entered the system through the time someone was alive.

You could accumulate a lot of it by providing services to people. Yet what you have will not go with you after you are gone. I'd say you should be able to pass your property on after your death but your currency would be gone.

Right now in our day UBI is poof printed out of thin air. It causes inflation that impacts everyone. It is backed by nothing.
