Both get you there, one faster and climate controlled, the other tiring. Why would I care about "agency" in that specific situation at a young age?

Because life is about the journey and not the destination. The destination (barring religious ideas) is the same for all of us. I enjoy running and walking as an adult since about hs age. As a kid I loved riding my bike too. Going at a slower pace leaves you open to whim. Let's you observe and digest your surroundings. Maybe you would see Cory. Maybe the neighbor kid you don't like that much had a bunch of friends playing frisbee in his yard so it was worth it to join. Or see there was a new kid and a moving truck. Or a turtle in someone's yard.

These days when I go for a walk, there is almost no kids playing or riding bikes or anything and it's kind of eerie.

Because one of those things is you acting on your own initiative under your own control, and the other is dependent on someone more powerful than you to grant permission and decide it's worth their time.
