You do not need UBI for that, you just need a few more options or packages for people to choose from, which would be trivial to provide.

More like one package per person. Of course that's still trivial to provide, as you say. You just give everyone a fixed set of points they can allocate to the options available according to their needs. I propose to call those points "money".

Even if you want a point system it becomes a separated currency from actual money.

But money is fungible, even among different currencies; think exchange rates.

What’s the value of a currency that can only be used to buy limited items?

"The black market for food stamps — where recipients sell the federal vouchers for cash — has grown by 30 percent in recent years, the Agriculture Department said in a just-released study. (...) In figures, sales of Supplemental Nutrition Assistance Program vouchers brought in $858 million in cash in the 2009-2011 period, compared to $330 million in the 2006-2008 time frame."

Somewhat lower because of transaction costs associated with barter and black markets but it still has value.
