This is confusing, you will forbid your wife from gambling even though you have no problem if she gamble responsibly and I do not think that a gambling wife will be a bad example to the children as long as she do her responsibility and prioritized it over her gambling activity.
What is mentioned is in my opinion and it all depends on the husband, even though the points mentioned by the OP and the point of his obligation to carry them out well are his rights and I am just giving my opinion.
However, I personally say that I will not let that happen because there is a possibility that several points of the wife's obligations will be neglected, especially in the long term.
I hope you understand what I mean.
