Interesting how artists don't make enough money from their creations, so our solution is to make certain information illegal to share, rather than give them a universal basic income.
If their art doesn't make enough money then it's clearly not in enough demand. It sucks but thats how things work. Only a small number of artists can ever coexist at the same time.
But to answer the actual question, I don't disagree that universal basic income would be great I just don't think that the above arguement is a particularly great one for it. There are many better arguments that could be made and I don't appreciate the false dichotomy that OP is putting out that because it just makes the whole idea seem hippie and stupid.
Also been aggressive with people who even marginally disagree with your opinion isn't productive.

Unless you burden the word 'enough' with far too much work in that sentence, then that implication doesn't necessarily follow. It is possible for something to be in great demand by those without money to spend. Furthermore, it is possible for there to be issues with the logistics between the source and the demand (e.g. demand is very physically distributed, or temporally limited and/or sporadic).
Money is a very particular way of empowering and aggregating only some demand. It ties the power of demand to history and not moral or egalitarian considerations for one.
