I see your point but if we're talking here about a lengthy marriage, where the stakes are really life-changing: the sharing of a mortgage-free home, life insurance policies, savings - that all takes 20-30 years. I would hope, that of after decades of co-habitation there is a breakdown, the friendship between the partners should carry through to a reasonable conclusion. If the breakdown happens in the first few years, there is little to lose.

It is seriously possible that a couple could be married 2-3 years, have it break down because of unreasonable causes e.g one person shows their true self, and then the other person must pay alimony the rest of their lives? If this is the case, then sure I'm in agreement with that being absolutely stupid.
