I purposefully put furniture because it can be a utilitarian box, or a custom carpentry art piece. Why is your brother art more valuable than a custom table? Or a delicious dish? Or the portrait I buy from the street artist that cannot rent-seek from it? With the best intention, it seems you are biased because we are talking about your brother's lifehood (but I'm still happy to discuss politely).
> IP protections are what incentives a portion of humanity to do something crazy like go to art school
Hard disagree, most of the art fields are first a passion and then a profession. People who go to art school is normally because they love it so much that they cannot imagine themselves doing something else, even though they already know it pays little. I've never ever heard of someone going to art school "because of IP protections".
One of the reasons it's so hard to make money is because there's many people doing it as a hobby that are already great at it, and so would jump at the chance of getting some money for it, leaving people who want to make livable wages outcompeted. Which is fine, this way society as a whole benefits greatly, sure it's unfortunate there are no more people living off it, but in exchange there are many, many amateurs experimenting and doing art, and from time to time one finds a formula that allows them to live off it (or "shills" to corporate).
