This is actually a thing in the EU (and the UK), because of the Artists’ Resale Right Directive. However, it has very little influence on the livelihood of artists, because the economic value of most art works peaks when they are first sold. So the people who benefit from the resale right are a tiny minority who didn’t really need it in the first place. It’s not dissimilar to copyright, where almost no estate gets to profit economically from copyright decades after the author’s death. Basically you get rules made for the appealing exceptions rather than the norm.
