There's a catch, though, and that is that you cannot use the money in any way that influences you directly.
And by that I mean that you can't list things like '1) Buy mansion, 2) Yacht, 3) Roadster, etc.
You can list things or come up with something that will indirectly affect you though. So if you want to start an aerospace company, then that's entirely possible, with the one rule that any money you make can't be used for you personally, even if the advancement of space exploration affects you indirectly.
That sort of thing.
And no, a trillion dollars is not that absurd a quantity of money. The US government spends almost 3/4's of that in a single year, just on the military. It's not an inordinate amount.
Kind of. Depends on how you look at it
