The referendums were in 1987 and 2011, respectively. Asking once every 15+ years seems fine, the population changes and opinions change.

It’s much less frequent than the usual democratic election cycle, where people are also allowed to reevaluate their positions.

But nobody asked, there hasn't been a third referendum.

		It doesn't work that way in Italy. A popular referendum can only abolish an existing law, partially or fully. The general public cannot vote to adopt new legislation.
