NO to SPECULATION in the world of ARTS

Times are changing: some investors having paid obscene amounts of money for a piece of art can not sell it for a still higher price anymore; the market is shrinking!
(Well, even if that's only temporary, let's contemplate the situation.)

Good!

Art belongs to mankind, and should not be monetized. Art is not meant to be useful, but only to generate emotions to the public. There's no room for Money here.

Fine; now I can hear your criticism: "Then how does the artist make a living? Do you mean we should kill Art?" No! Of course not, this is not the point. There IS a solution to this dilemma: the artist should be paid the first time he sells his creation, so that s/he can indeed make a living out of it. At this stage, we can say that the buyer follows his emotions, rather than speculative goals, even if the action of buying does give a measure of those emotions on the big scale of Money (sic).

BUT THEN it should not be possible to sell this creation a second time following speculative goals.
