The site assessment and design will determine the specifics. Electricians are not design engineers, nor are they lightning specialists and therefore should not be offering solutions, which do not fall within their scope of expertise. It would appear (reading comments on social media) that many electricians feel that one size fits all and every application is exactly the same, you will even be rewarded with certification once you have completed a certain number of installations.
If the design criteria specifies an earth spike, it should be installed.
Would an earth wire fry, it would depend on the intensity of the strike. Without testing the resistance of the earth wire, you would never know the impact of the strike. It may appear to be ok, however in some cases the wire could reach such extreme temperatures that it would render the wire pretty useless.
If you have been in the electrical industry for a while, you would have noticed wires which are no longer "shiny bright copper" , they are not as flexible and turn a blue/black colour, they should be replaced.
