You're saying that free money creates inflation but that's not true. Like I said, before dismising it, go inform yourself on whet it is you're talking about, ubi has been studied for decades now and when you say that

Usually, places that try the UBI end up halting the program because it's not sustainable

That's a fairly recent article and, it hardly would make someone conclude that it was because it's not sustainable. In fact that is the bullshit rhetoric, word for word, that the "thieves" (as you surely suggested),use. What we find, in experiment after experiment is that ubi works, across the board. It creates more consumers, it gives people a chance to vote with their pocket, it let's them employ other people and to keep the demand up. Nations do not have money?

You know why the colonies went to war? No, it wasn't taxes. It was the lack of money. It was what having to pay taxes with Scarce Gold and Silver Coins created, leading The Most Prosperous Economic Times in History into rampant extreme poverty. It was not for the lack of labor, but the lack of money to buy goods and services, which dried up jobs and producers, and which led to massive unemployment that destroyed wealth. Money in proportion to the economy, that is what the thriving colonies recognized, yes some has hyper inflation but Franklin knew what he was doing when he recognized the genius of "money in proportion" so as to have enough for the free transaction of goods, because it's not only too much money that destroyers a nation but too little as well. Then again, he readily recognized that taxes are voluntary, something I think you'll die before considering it.
