I just saw the posts and video about the effect of stray currents in gas pipes a bit scary to be honest but interesting nonetheless I was thinking that maybe a new rule should be that allgas pipes must be plastic coated where they enter the ground. Now I know if a gas pipe gets broken its likely to tear the plastic but its better than nothing.

Connection with true earth is only small part of the problem - a bigger one is connection to the earth of the supply elsewhere - e.g. via bonding in a neighbouring property. To stop that you'd need a complete break in the continuity of the gas pipe.
