Well, it is not that bad, thankfully. Just imagine a friendly soccer match between two village's teams. Putting in your damndest to win it is already a significantly more difficult thing than everyday life and creates bonding between team members.

Since life started to get too easy for some people - and for some people, that was really long ago - they started to generate artificial difficulties to make things more exciting, sports, games like poker, gambling, and so on.

Then what am I even asking? I am mainly just confused by choice and return on investment. Suppose I have not much interest nor time to invest in learning hobbies, yet would be willing to pay this tax for bonding, and would be looking for a team activity that feels difficult and uncertain enough to generate bonding. The kind of thing people later brag about. What would be the most effective one, I wonder.
