You don't mention the fact it's completely unworkable mathematically. In the UK I believe it'd cost £240 billion a year. Where the hell would anyone be able to find that money from? (Tackling tax avoidance from Starbucks isn't a credible answer). Just to put it in context, that's twice the entire NHS's budget, or 5 times our defence spending.
We wouldn't need money for most benefits any more (pensions, income support, etc) so that's about £120bn of the £240bn found immediately. You mention the NHS - we'd be able to spend a lot less on that if people didn't have poverty-induced health problems, so there's another £35bn (assuming a 30% reduction of the £110bn). It's not unreasonable to assume that the difference of £85bn would essentially pay for itself by…
If the idea is to give everybody money so that you can tax it more, you're engaging in economic waste. Without being able to increase productivity in other areas to cover the lost value, you will, hopefully slowly, but eventually trend towards zero, and a failure of the system overall.
Encouraging economic productivity in an environment in which nobody has to be productive may or may not be possible, I honestly haven't any idea, but its certainty doesn't seem terribly obvious to me.
