It's always a choice, but your scenario is still different from what I'm talking about and you clearly had a lot more freedom than most people in religious households have. For many kids staying at home isn't an option as long as you are living under your parents roof, the same as not going to school. While one is illegal and the other isn't (in the US anyway), parents would still intervene with your "choice" and get you back in the church. Then there's also friends and other relatives who would pressure you to go, in addition to fellow members of any church programs you were involved in (Jr. Ushers, Bible Class, Kids Choir, Private Church School, etc...).
And that's if you get into this thought process. With that type of community surrounding you at all times, most people just go with the flow/just fit in and don't think that much about it until they are much older, if that.
