Although some may argue that money can't buy happiness, in todays society, money is almost always a necessity.
One thing that money can buy is actually freedom. Freedom to live independent of money. Freedom to spend your time without worrying about your next meal.
Money can also be used to buy or save time.
The only people who would say that money isn't important, are definitely people who aren't a part of modern society or grew up in a decently well off household.
Even simple tasks such as world domination require a hefty startup capital. At least it's easy to find "willing" individuals who decide to generously donate their whole net worth before disappearing forever. 😃
