Having access to an audience is not the same thing as capturing an audience and it is a giant leap to being economically supported in these endeavours.
Any artist who can't self-fund is going to have to create art that sells. This is a fact of life that has always been true and will be forever true in the future. In the past artists depended on wealthy patrons which might have eliminated the need to sell art to the masses but still required that art could be marketed to the patrons. Today artists have more options because they can reach wide audiences for little cost and have access to revenue streams such as YouTube ads. A world where artists create art that no one wants to buy is a pointless fantasy.
