Oh, you're one of those people that worries about the value of the US dollar like it's not entire world's reserve currency already or a measure of American "strength".
I think what he means is if you give some one $1000 for free, they will only do a job that pays say $2000.
Because people want more salaries, it costs more to produce/service a thing. Therefore you have to sell your products/services at a higher prices. Now the $1000 you gave for free is less valuable.
Now come to think of this if your $1000 is less valuable. How much is $26 trillion worth debt valuable now? The people to whom the debt is owed are screwed.
Also once you do this you will have a hard time raising money next time when you need it.
Basically. Things like UBI aim to be the 'perpetual motion' equivalent of economics. The fundamental problem seems to be you can't pull anything out of nothingness.
Its status as the world reserve currency makes the US dollar very resilient right now, but what happens if or when that stops? Do you think it will always stay the reserve currency forever and ever?
Let's not forget how the US dollar became so strong in the first place. It probably wasn't because we gave a lot of people money to do nothing of value, and it wasn't because it started its life as a reserve currency from the very beginning.
