I agree with universal basic income and also believe it will cause issues. The only way it works is if regulations are put in place to avoid making it useless. The rich can spend large amounts to find loopholes so basically the government will have to provide a bunch of guidelines and when the government steps in people get mad. Even if the pool of money is the same, the pool of money in each market may not be. Stocks and Yachts (extreme example) may go down and investment in rent or cheap food would go up, therefore demand and therefore prices. An alternative would be to make UBI use a separate commodity but it wouldn’t really fix the problem as it would likely mean that the commodity could only be spent in select stores and there not provide the freedom it should.

Unfortunately, its a matter of needing real investigation into the market as there’s a chance it could drastically backfire.
