It need not be moralising at all. In many countries for pretty much every "life changing" contract such as marriage, buying a house, changing the will, etc. there's a cool down period that tries to prevent being rushed to do such things.

Also here in (some cantons of) Switzerland, during the month of notice you have to give to get married, the names of the couple is published so that people can protest the marriage if they know it's not a legal one, which is for sure something some people can find odious but it's not done for moralising but for practical purposes.
