Unfortunately it doesn't work that way. Things at home are the same every day. They may be fun for first 5 minutes but then, well, they are not. Outside - city streets, playground, park, forest, you name it - there are unlimited amount of "toys". Everyday new, everyday exciting. You may go to the same place but people are different, animals are different, rocks are different, sticks thrown into stream are flowing differently every time. My kid is bored at home, even though we have way more toys than we planned to, and she's craving for full day walks. She's bringing me her shoes in the morning and points at the door. She's explorer and there are plenty of opportunities out there.
