A big part of the problem education systems are solving is not "how do we get knowledge to children", but "how do we get masses of children to learn without coercion of the ugliest kind".
Some children are innately motivated to learn. Some are motivated so strongly you could give them a smartphone and watch them learn all they need to learn in life. But those children aren't the norm - they're the freaky 1 in 1000 outliers. And education has to work with everyone.
Thus, peer pressure. That's what putting a whole bunch of students in the same room accomplishes.

I worked as a teacher for a year. Children are innately motivated and curious (this is not just a cliche). If there was any laziness it usually stemmed from fear of not being good enough but they definitely all tried, even students that didn't know their 5 times table by age 10. Some students have greater self-perseverance than others though, some can't handle being wrong and fear being seen as less-then their peers. Others like to challenge themselves without such fear.

I don't think I've met a single child in my life that isn't excited about learning about new stuff, but it really depends on what it is, it differs a lot! And they're all different as well, someone who's really into math might hate history, or vice-versa. But they all want to learn something, in my experience.
The problem occurs when you place them all in one school, and force them to learn everything, even things they don't want to learn about, and that kind ruins the other parts they actually find fun and engaging.
