While you yourself might not be directly involved with this, a lot of what makes capitalism go round ultimately goes back to these large institutions swapping vast sums of money around and market makers help facilitate a lot of that action.

Business loans, your savings account, your employer’s (or contractor’s if you’re freelance) line of credit, the global currency system, the prices of commodities that get turned into the physical products that we consume, etc.

Well, that’s the idea anyways. Whether or not the snake has consumed it’s own tail is a whole different discussion, but the stated value of stuff like this is to create efficient markets with correct price/price discovery aka make sure no one is paying too much or selling for too little.
