Welcome to SteemIt.
No offense meant here, but if Universal Basic Income was such a great idea, you would not have to dedicate your life & make Herculean efforts in trying to promote it.
For instance, take cryptocurrency - an idea whos' time has truly come. It will not be stopped, because it is a superior idea. Because of it's very nature - the intrinsic properties of blockchain technology - it will be adopted and implemented by free-thinking, freedom-loving, powerful individuals - and it will radically change the world. I don't have to "convince" anyone that cryptos are a good idea, because they will discover that fact for themselves over time.
UBI, on the other hand...? I'm not convinced at all, and neither are a lot of other people. What works really well in a small, poverty-sticken nation such as Nambia does not necessarily work well in a large, industrialized nation like the USA. UBI, by it's very nature, lends itself to a top-down process which will inevitably breed corruption. Blockchain technology is highly resistant to corruption.
We just had a "crisis" with BitCoin - and its' corruption has been avoided, for now, because of its' properties. UBI is an economic theory - a largely unproven one, at that. It may work well here or there, in a microcosm, but it is not by any means a proven system ready for worldwide adoption - I don't think. At the end of the day, it may have to be imposed upon people, against their will. That is not the hallmark of a great idea.
The reason you have to convince people on the merits of UBI is that Joe Public believes (rightly or wrongly) that it will cost him something. Creating a new cryptocurrency doesn't involuntarily cost anyone anything. There's also the reality that most people have no fucking clue how money or the economy works. If they did they might be far more amenable to the UBI idea. Finally, there's also the silly moral angle that it's somehow wrong to get something for "free". When most of the population are too thick to consider that morals may not be objective and absolute, it's no wonder that you have to convince people of this stuff.
