What happens when common law goes bankrupt?

What does this question mean? Common Law is a law that is by definition so common it is often unwritten in statute. In England murder wasn't enshrined in statute being a common law.

Common law examples are right of 'ticketed entry'. i.e. you have the right to enter a shop or mall, but that ticketed right could be revoked, and you are banned from that shop or mall as if the the implied 'ticket' had been taken from you.

Another example is the common law right to make an enquiry at a front door of any house, but if you are told to go away you must. this begs the question of gated communities which take away that right.
