Why do you do anything that bring you pleasure when you could be working every waking moment?

No fun, more work!

People that play games, as you call them, like to see people play a high level of that same game, because they enjoy the said game.

It applies to pretty much everything in life. This is one way we learn.

And how do you make sure that people that are good at whatever game gets to the highest level possible? You pay them to professionally play the said game.

Pretty obvious. You don’t wear your nickname well.
