This seems highly incomplete. Millions of people play football amongst themselves. Only looking at professional footballers is just the apex fallacy. The fact that a few people are paid to play doesn't negate that cultural reality.

Even then they are voluntarily playing football as probably by far their best option in life. Paid for by hundreds of millions of people who want to watch the best football possible, and will pay for it.

Finally, people choosing to pay for things isn't capitalism taking over culture. Everything about football requires money: paying for a football to go for a kickaout isn't hideous commercialism.
