The only agency which such right is the government, if the government decides to ban gambling, then that's it, in a country where there are multiple religions, each religion can impose laws only on those who are members of that religion, and on this adhering is based on personal choices and so on. But when the government of a country creates a law, every body from every religion is expected to adhere and obey that law.
Even though Christianity has the largest following in the Philippines, the government can't make decisions based solely on one religion’s teachings. But in reality, most religions discourage gambling anyway. The thing is, gambling has already been deeply rooted in our culture, even during the Spanish colonization, they introduced cockfighting, which is still hugely popular today. And while online sabong was eventually banned, if they see online gambling as just as addictive, then they should be consistent and crack down on that too.
I think the government doesn’t really see it as a major issue yet, maybe because they're still providing financial aid to the poor. That’s why many of the people who are most affected by gambling addiction just continue, thinking they’ll always get some support from the government anyway.
