I don't think you could ever have an amount of money you couldn't do anything with. Even if you had $100 billion, as Bill Gates shows their is plenty you can do with it. I think I would head down the spaceX path if I even became mega rich. If government no longer wish to fund space exploration it would be great to take up that role and push humanity forward. You could never have enough money with a pursuit like this.
