This is what I was talking about. It will always depend on our own understanding and situations. While others see financial stability as being independent from their parents' financial help, other may view it as being able to buy everything they set their eyes on without worrying if they'll have the money to survive the next day. We all have different backgrounds and community that influences the way we see and understand things such as financial independence.
And for me being financially stable is no longer having debt and having Bitcoin investments also stock investments whose dividends every year can be used to pay for life when I'm old. Indeed, everyone has a different understanding of financial stability, because as you said, how we are educated and where we live will greatly affect our mindset about finances, but for me having financial stability when old is more of a priority because when we are young there are many things you can do to produce and it is very limited when we are old, so stability must be started when we are young.
