The problem with UBI is inflation. Give everyone another $1000/month (or whatever) and all you've done is make every existing dollar in the economy worth less.
This is exactly the question I don't see answered. How will you handle increased prices? Unless instead of $1000/pm, you give an equivalent purchasing power/quota based on normal/average/reasonable per-capita consumption. Like a token that allows you to buy a certain amount of food/clothes/medicines etc. So what happens if I don't need to buy anymore clothes today but need more medicines but another guy is in a reverse situation? How about we translate this purchasing quota into points and have an exchange for people to trade them? Did we re-invent barter system/money in another form?
Make the UBI micro-adjusted (month-to-month) for inflation based on a consumer index - and so indirectly tax passive capital (which is only earning meager interest)?
