> just means someone would like to UBI exist without necessarily having to be an expert on how to implement

I would like eco-friendly flying cars to exist so that I could avoid traffic in the morning, I think that would solve all the mass transit and infrastructure problems in major cities.

No clue how to build one but I'm sure that 500 experts should be able to accomplish it if they really tried it. Until they do that nobody is allowed to question the validity of this universal solution to all transportation related problems that humanity is facing.
