Sure, all that, but at the basis, the removal of a barrier does make it somewhat less safe, even if it's still on the individual to basically make the decision. If you are walking across a bridge and there's a barrier on the side to make sure you don't accidentally fall off, it makes things safer, and if the barrier is revamped, you can still be safe by being careful, but at the same time the safety of the barrier was there (even if you didn't really use it) is no longer present.
