So if both hold tight to gambling while nobody quitting, then what view do you think the society will see such family where both husband and wife are gamblers? Because one true fact that remain is that no matter how both tries to gamble responsibly, inasmuch as both keeps gambling and happens to have children, there is a higher tendency they having one child who is an addictive and chronic gambler, which is the least thing any parent will ever want from his/her child. Hence, one quitting will go a long way curing such menace.
But unless if we are talking about a moderate gambler who do not gamblers all ways, but if we mean full-time gamblers, then both parties are not suitable to be husband and wife.
I think it's awkward. 2 Husband and wife are both people who like to gamble, and they see gambling as an entertaining game. The best solution is for them to teach children from a young age to know about gambling knowledge. Guide children towards healthy gambling in the future. Because even if you ban children, they will learn about gambling later because gambling is now widely advertised online. Teaching them about healthy gambling is probably a safer way.
