My art is the only thing I have that is irreplaceable, but screw it, with $2.5 million, I can remake it. My ceramic sculptures would be the most painful to lose, since I'm not much of a sculptor and most of the good ones were just dumb luck, but I could get my own kiln with that kind of money and do whatever I want. Heck yes.
In practice, though, I wouldn't trust some dude that just comes up to me with fantastic offers. Even if I thought he would really do it, where is he getting this money? Why give it to me? How does he know what I own? Is he magical? If so, how does magic work? Are there other magical people in the world? Is this deal even legal? Would the $2.5 million just appear in my bank account? Would I have to pay taxes on it? I feel like the IRS would get really suspicious.
