Knowing the complications of just being alive, irrespective of financial state, I'd be willing to take that risk.
You’d have to rearrange everything about your life. All sorts of people would come out of the woodwork to scam you, distant cousins you’d never heard from would get in touch; resentments could grow between you and friends/relatives you have been close to who expect you to share it all. You’d be a possible kidnap/ransom target, have to worry about financial managers or accountants trying to steal from you; and you’d probably get audited routinely.
I guess I’m old, but I don’t need all of that. A million would be nice; but except for the ability to contribute to some worthy charities, hundreds of millions would be a burdensome mess.
