Congrats on your fundamental understanding of how insurance works. Indeed, insurance is pooled risk. All pay into it and some will utilize it more than others. Maybe you won't utilize it much but your sibling will. It is just like car insurance, it doesn't drop to zero if you do not have any claims. It is a guaranteed fact though, that the vast majority of us, over our lifetime, will consume almost as much, or more than we put in. That is why insurance companies invest premiums to make the pool larger.

I guest next you will argue that since investing is a zero sum game, when insurance companies are up on their investments, the guy that is down is getting screwed.
