why should it be worthwhile and why should it add value to society? if registering were free i'd see your point or if not everybody were allowed to register

how would you play football? for every goal a team scores you have to score an own-goal or let the others score because it would be unfair otherwise?

Football is a competitive zero-sum game. Someone wins, someone loses.

The world isn't like that at all. Everyone having enough to eat is strictly better than some people starving and some people having twice as much to eat.

Football is not an end in itself. People play it because it's a fun social activity. You can easily play football in a vicious way which, while still entirely within the rules and increases your chance of winning, diminishes the enjoyment and social connection which brought people together for the game in the first place.

Similarly, economic activity is not an end in itself, and economic strategies should be critically examined for what they contribute and diminish in the communities where they're adopted.
