Because Monster Hunter has been built about teamwork from the beginning and it shows in every aspect such as rewards being balanced to encourage it and the actions of every hunter mattering.

Going into MH with the idea that you should only be looking out for number one is frankly a toxic mindset and I suspect the creators would agree with my assessment.
