I feel like the word retirement has a totally different meaning in the 21st century. I doubt anyone actuals "retires" anymore, it more like financial freedom to just pursue what you want, when you want.
I'd happily "retire" onto a nice plot of land and fix up old cars, it'll be hard work but I'll be doing what I want knowing I've already secured my financial freedom.
Just my 2 cents

If we talk about normal retirement then this is clearly different from Financial Freedom. Because the concepts of the two are clearly different.
But if we talk about someone who has managed to collect a lot of money and it is estimated that this money will be enough to meet all his needs for the rest of his life after he stops working. So he decided to stop working even though he was still young because he was confident enough that the money he had would be enough to meet all his life needs after he stopped working. And the conditions are indeed a bit similar to financial freedom.
But still the concept is still different. But people who are able to achieve early retirement should be people who are good at managing finances and have made thorough financial preparations. But still, someone who retires early does not necessarily have financial freedom. But people who already have financial freedom seem to have much more freedom in their lives. He is free to retire at any time because he no longer worries about money. But people who retire early actually only have more limited finances. That is limited to the finances they have collected or something similar. But they don't really have financial freedom yet.
But I feel that people who are able to reach the early retirement stage are people who are close to the next stage, namely financial freedom.
