Most collectivist cultures approach the family something like a corporation. It’s not about leaving, it’s about gaining in power and influence as you rise through the ranks.
Just like in the working world, though, conflicts arise when your personal mission statement does not align with that of the corporation; or your personal culture (needs, values, worldview, etc.) is not harmonious with the general culture of the corporation. That can present serious obstacles to ‘rising through the ranks’, taking on more power, getting more respect, and so on.
Your original posts sounded like you are pretty ambivalent about leaving. But while you are working out your position on that, an appropriate interim goal would be to get yourself to the point where you can contribute financially to the family, and work towards financial, if not residential, independence. You’d need to work out your own ideal approach to that. How much you keep for yourself and how much you let them in on.
You know your family best, so you’ll know if the above idea is even workable. For example, if you think you’ll resent them too much or that you’ll have too much trouble maintaining appropriate boundaries around time and money demands, then maybe go for some other strategy. But it is one of the traditional routes to individuation within a collectivist family system.
