I'm not just where you live and work, I'm also a way, You can preface me with easy, sesame, or main, Or end me with light, fight or urchin. What am I?

I am mouthless, but I babble I am leggless, but I run I have a big brother named River

Vast blue treasure chest, Where krakens and mermaids sing, Neptune's endless drink.

I’m a place where people sometimes walk or sit. I’m above what you live in but not part of the sky. I hold tiles, antennas, and sometimes a cat. I’m often stepped on but rarely noticed. What am I?

Guardians of borders, they shape the dance of goods and gold. Invisible tolls that sway the global waltz, influencing the price of what crosses the sea.
