I'm out of mod-points right now, which probably is a good thing, because i'd have modded you "insightful" on impulse. That probably would have been wrong, since your scenario is not universally attractive, But boy did you hit my personal idea of unlimited whimsy.
One addition, though: I'd first buy all my favourite works of art (as and when available), then pay the master art-forgers of this world the requisite monies to create exact, indistinguishable replicas of them. Then, when it's definitely impossible to distinguish between original and "fake" I'd donate half of my collection to the public. Which version goes to the museums and which version remains with me would be decided by double-blind random events. Who owns the original? What is the original? Who cares... the bottom line is: a lot of extraordinarily talented craftsmen (and -women) would get payed well for their work, and some of the greatest works of art would now exist twice. Ah... what a wonderful world that would be.
And the best thing: those shenannigans, costly as the might be, would likely only use up a tiny fraction of my vast fortune, leaving lots and lots of money to be spent on serious, humanist causes. Which would get me tons of karma, but would be utterly depressing to manage. So (since I'm so incredibly rich, remember) I'll just pay people (administrators) to care. And some other people to audit them. And, maybe, some people to audit the auditors (I don't mind losing money, but the people who should receive it might). Yep, I thing that would be A Good Thing(TM) all around. :)
P.S.: Yes, I'd own the Trademark on "A Good Thing", too, but would only enforce it when evil fucks misuse it. See how nice I am? :)
