There is nothing inflationary about UBI. It's interesting how people think the onus is on UBI proponents to justify why their policy wouldn't cause inflation. Even if it did cause inflation, ultimately it's just a redistribution of wealth, and it still helps those most at the bottom.
You mention Venezuela which is a totally different scenario. They had an economy overly dependent on imports paid for by the revenue from oil exports, so when the price of oil crashed, so did their economy along with it. With resulting large amounts of foreign denominated debt, their only options were to 1. default 2. print money to pay off those foreign-denominated debts. They went with option #2, and their currency collapsed. Furthermore their country has extremely weak property rights (eg. businesses being seized by the government), enormously high levels of corruption, and ridiculous price controls.

Now what does any of that have to do with UBI?
