Are you referring to the classic LEGO or LEGO kits? Those are two different thing. I am using LEGO kits as a reference and analogy, not the classic LEGO blocks.

I don’t disagree that the classic LEGO blocks give you tons of creativity and room for exploration.

While LEGO kits just have one end goal, which shown in the packaging. The example would be: Make a flower, or make a batman car. That's what LEGO kits are
