Financial freedom is supposed to cover more than just some standard "cost of living" in a given area. It should let you maintain your lifestyle without having to work for it. Maintaining the lifestyle includes keeping your spending habits, so if you have been spending 10M/year, then achieving financial freedom would mean you can keep spending that much for the rest of your life.
It's a different question how many people actually spend 10M/year - I have no data about that, but I can easily see myself spending that much if my income has been 40M/year for several years. To me personally spending that money would not necessarily mean buying some high-end luxuries. It would probably involve trying to make some changes in the world and influence things. But yes, luxuries and interesting experiences too. If you're interested in this question, try finding more information about lives of famous rich people.
