Spoilers: it's not a better idea because it means-tests based on "lost your job due to coronovirus-related reasons" which fails to encompass literally the entire self-employed gig economy who will never formally lose their jobs, because they don't technically have jobs.
It also doesn't encompass people who aren't fired but aren't getting hours or salary and people who weren't working but have had their support network collapse.
Worrying about rich people accidentally getting some extra cash is a waste of time and effort. The number of people who really have no use for an extra $1000 a month is dwarfed by the number of people it would literally save.
The only criteria for UBI should be "do we know who you are and how to get the money to you?"
