And even if you don’t have a few of the immutable things here such as the colour of your skin…

These situations could always happen in the future. Your brother can find out he’s gay, your parents might get sick with cancer, you might fall in love with an immigrant, climate change will have an effect on you, and so on

Not only that, but any of these could be you too. You might get mental health issues or get physically sick, you might find out something about yourself, even well into adulthood, or lose your job, or face a natural disaster, or any one billion of things that you need support for

Humans are not evolved to be truly independent. We all need, or will need, support.
