Ask him why he won't play call shot/call safe either!
Edit: I can't see his reply, I've had him on ignore for years, due somewhat to his attitude toward this topic. Usual whine is: "Why should you get to push out when I play a good safe?" My reply is usually: "Why should't I get to push out when you miss the pocket by two diamonds?".
Coz i will guarantee i will miss by 2 diamonds far less than I will play safe within inches of my target, duh? Surely, not with a high enough frequency to design a rule set that would allow you to push every time you come to the table.
Your contention MIGHT hold water for low level players, but really, they play so bad that it really doesn't matter what rules are used.
