Ordering a pizza I otherwise wouldn't have with the money would not be my current life. It's a question of degrees. If I win a 100M lottery and do literally nothing except hand it over to my financial advisor to invest at a modest 4% return and draw a generous 500k salary from that I would still be making 3.5 million compounded compounded per year.

This is more or less how retirement works so it's a pretty well-trodden path.
