Unfortunately regulation does seem to be mostly written in stone. Sure, things can drastically change in events like revolutions but I'm not holding my breath for that (nor do I think that kind of instability is something good to have, it's essentially a huge regression with the opportunity to "redo" things, but as humans we ALWAYS do the same mistakes again sooner or later). How many laws are we re-evaluating every few years and updating/changing them as necessary? I think if we had almost all laws passed with expiration time it would hopefully result in better/more up to date legislation although the only "temporary" legislation I remember (Patriot Act?) was just passed every time it expired...
