There are experts out there who strategize around these kinds of things, and we're very fortunate to be in the 21st century, with online availability as it is. One thing you might consider, because I'm definitely not in the camp of “let's go to a referendum”, is to come up with a strategy to try to engage the population. People have talked about citizens' assemblies and all of that, but there might be online ways to get people to engage. That would take some creativity.
I thought the way in which the government rolled out the census strategy was quite engaging. People actually did step up. It was mandatory, but the way it was done was interesting. So there are creative ways to do this, and maybe we need to look to third party experts.
