"Overall basic income is theft from workers and will be seen as such by those workers."
When enough of those producing wealth decide that UBI = theft, they aren't going to just continue producing without pushing back. Personally, if UBI is implemented, I will "go Galt" and move to a self-sufficient homesteading-style life, leaving any cash-requiring activities (like paying taxes) to my $UBI/mo check. That I am a productive person does not mean my productivity will necessarily be taxable; I grew up in a live-off-the-land family, and would be happy to return to that lifestyle if you're going to just take a big chunk of my income just to give to others.
There are enough jobs (yes, there are). Wealth is not durable (you eat a hamburger, $1 of economic wealth turns to *). Encouraging idleness by funding it is an unsustainable economic strategy, because so many people find paid idleness a desirable lifestyle.
