During the summer, our kids followed our city's curfew times. That made it the "law" not just our rule.
When I raised teens last, cell phones were still new and they didn't have them. My 9 year-old has a cell phone, and I don't intend to ever take it away from her. She does not have text capability. My daughter will have access to FB, but I will be one of her "friends" so that I will have access to what she's doing there.
My 9 year-old already rides her bike to friends' houses, with our permission each time and a designated time to be home, and a phone along to check in if necessary.
By 8th grade, a young person should be in charge of their own homework. We had occasional times, with my stepson, where even in high school he needed our guidance on homework. But it was more about asking him to come up with a plan to catch up and then monitoring the status of his plan. It was not us daily being in charge of him completing his homework, or checking his work.
I'm a parent that believes the young people need more freedom AND more responsibility at the same time. When I and my brothers were 13, 14, & 15 we were left home for a weekend with 26 cows to milk and a farm full of animals to feed and care for. Along with our own meals to cook, etc. And we did it perfectly well. Now many parent treat young teens as incapable and incompetent, so that's how they act. In France, age 3 is the standard age for a child to be old enough to go to the corner bakery each day to pick up the family's bread...
