Why can't I live the way I want to live?

Why can't I be free to live as I see fit, as long as I don't harm anyone?

"It's time to see what I can do,
to test the limits and break through.
No right, no wrong, no rules for me,
I'm free."
- Elsa from Frozen.

We continually push the envelope and redefine society to match our cravings to be free, but is it good for a person to have freedom to do whatever he or she wants? And how does God fit into the picture?
