> Arguably, that saves even more money than trying to only give it to people who "need" it.

Some people argue this, but never with reference to the actual data, which unambiguously proves them wrong. The UK Department of Work and Pensions' unusually bureaucratic approach to eligibility results in admin spends of a little over £6bn, or around 3% of its total budget. If you could eliminate all those costs you'd be able to pay working age Brits a UBI of around £180 per annum!
