silking spawners

Ok so i've just accidentally broke a cow spawner with a pickaxe.
It's eff5 so it broke so fast the warning hasn't even shown by the time i broke it.
This got me thinking, why would someone break a spawner without silk touch?
Logic dictates that unless you are griefing or is wanting to waste money, you wouldn't breaking spawners without silk touch as you won't retireve it, and they are worth quite a lot of money. Hence, it isn't desirable for the player, and would decrease that particular player's ingame experience.
Hence i think that a setting should be add in /sett that makes you unable to break spawners without silktouch or for people under the rank of vip, with the default of "on".
Thank you.
