The advantage of using the Wikidata list items for this purpose is that you have some control in presentation, whereas live queries have a haphazard list order based on date-of-creation-of-the-Wikidata-item
Then, isn't the solution to build better tools instead of duplicating the information ?
Maybe something like Crotos ( http://zone47.com/crotos/ ) but for monument. @Magnus : sorting Autolist results wood be great (I'm too puzzled by the « haphazard order »).
@Jane : It's kind of counterintuitive but in the long and the short terms, manual list are a harder and messier way to build list (that's why Marteen build the Erfgoed databse in the first place) and that's a barrier to entry too.
