I believe, and I might be wrong since I am far from an expert at these things, that what the OP meant is not that divorce should be trivial.Im disappointed with the OP, I know its not intended but we shouldn't encourage inadvertently the 'casualisation' of marriage. We know where it can lead.
My understanding of "no blame" divorce laws is not that people can casually divorce for no reason. But that traditionally countries required one spouse to officially blame (as in on a public record) the other for something in order to ask for a divorce. This leads to court battles over children and money. And ends up costing more money than it is worth and causing even more stress for everyone in the family. The idea of it being "no blame" simply means that if there is an issue that they consider is serious enough and that is unable to be fixed, both husband and wife can both agree to divorce without publicly stating the other one's wrongdoing to the government.
Naturally, a divorce is a VERY serious thing and should only be undertaken as a last resort if there are no other possibilities and everything has been tried to fix the issue.
