Money supply isn't what's causing today's inflation. What's causing today's inflation is price fixing and insufficient competition.
In a properly functioning economy, businesses (including landlords and grocery stores) set prices based on what their competitors will let them get away with.
In today's economy, there are no real competitors, and businesses instead set prices based on what customers can afford.
Unless and until that problem is solved, UBI won't work.
