I don't see an agenda behind Unconditional Basic Income and my intuition tells me it will never be implemented because it's too great a threat. We're more likely to see universal credit/income which is something else entirely. All are still based on a monetary system which also creates problems. Using crytocurrencies aren't necessarily going to solve issues either because either way, the banks will look for a way around it.

Meanwhile, many of those stuck in the system continue to suffer.

I'm not sure who is saying drawing pictures is going to be equally important to a starving family as food is ... I'm confused about where you got that from @Cahlen. I don't believe everyone wants to paint pictures. Secondly, most people would want to work to supplement the unconditional basic income as they'd want to continue living in conditions they're used to or prefer. UBI is not going to be enough to cover some aristocrat's rent in London or Manhattan. It might promote people moving to the countryside and setting up homesteads and farms though. Lack of jobs/survival money is what drives people to cities in the first place.

Thirdly, people generally want to contribute in a meaningful way that benefits society. Just because one person like to draw, using your example, does not mean they won't want to grow food. UBI affords people the time to explore their options and the reality/fantasy behind it. Most would end up doing something that works for them and society.

My post was comparing UBI to another scheme for basic income and not taking into account that moral issues of taxation at all. At this point, I don't have an opinion on the matter yet.

ps: This is not going to sway anyone who thinks tax is theft or that there is an agenda but it explains something about wealth distribution and work issue.
