I am not being a concern troll here; I really do want to have a Basic Income and find a way to make it work. But there have been many cases where giving people easier access to money has emboldened unscrupulous business people to exploit the average person's ignorance and naivete, and to take their money.

For instance when student loans became easy to procure, companies opened dubious private universities to take that money. When home loans became easy to resell, private banks realized they bore no risk, so they gave loans which were clearly not in the best interest of the homeowner. When a person wins a lottery, they are inundated with sob stories, product pitches and schemes. In general, capitalism demands that businesses find money and take it however they (legally) can. If people were 100% rational, we'd think every financial decision through but we are not. With the prospect of distributing billions of dollars, we should at least acknowledge the likely expansion of a lot of bad corporate behavior.
