It can be done mostly right but isn't in many places in the USA where ballots are sent to everyone on the voter records no matter whether they still live there or even live at all. Where there are no or insufficient checks on whether the ballots are filled out by the registered voter or by someone else. The is plenty of documentation on this, if the news sources you follow don't report on this you're missing part of the picture.

The real strawmen are the reasons given for not requiring ID when casting your ballot. Here in Sweden there is nobody who complains about having to show ID when casting your votes, nor was this ever a problem in the Netherlands.
