I'd immediately publicly donate it, or burn the ticket before collecting.

Do you really want a target that big put on your back? You'll spend most of it on physical security from people trying to break into your home. If you decide to spend it on a new house in a more private location where you have the security, the funds will be depleted before you can gain the income required to maintain said house/security.

It's not a 'curse' as a lot of people put it, it's just impractical for one person to be given that much money all at once with no supporting income. You aren't a real billionaire at that point, as most billionaires have long developed empires and diversified assets. It would take forever to build that sort of empire from a sudden influx of a billion dollars while simultaneously trying to defend your life.

I find it weird that people pay money to have an impossibly small chance to have their life ruined. Best case scenario you are out $2, worst case scenario you're struggling to stay alive.

The worst part about it is that poor people are the main players of this 'game'. So that means you are losing money you desperately need to survive for a chance to be the worst at managing said money.

Just think about the quantity for a minute, at $200,000 insured bank accounts it would take 6500 bank accounts to keep that money insured. One person cannot do all of that, and probably not even 100 people could either. Most people think and are recommended to hire an accountant, but that's really not enough. You'd have to hire a staff, and at the same time try to immediately find a way to figure out how to start making serious guaranteed steady income to support said staff.

My daydream is a world where the government doesn't prey on it's citizens like this with a false pretense of being 'the good guy'.

The only way to win is not to play.
